Abstract: An attachment unit for attaching a second device to a first device includes a first attachment member and a second attachment member. Each of the first attachment member and the second attachment member has first to Nth engagement sections. N is an integer of at least 2. The first to Nth engagement sections of the first attachment member respectively have the same shape as the first to Nth engagement sections of the second attachment member. The nth engagement section of the first attachment member is engageable with the (N−n+1)th engagement section of the second attachment member. n is an integer of at least 1 and no greater than N. At least one of the first device and the second device is an image forming apparatus or an extension device.

Abstract: An image forming unit of an image forming apparatus includes a developing device and a toner replenishing unit that replenishes the developing device with toner. The toner replenishing unit includes an upper toner container, a lower toner container, a toner conveyance unit, and a replenishment control unit. The upper toner container and the lower toner container are disposed adjacently to each other in a vertical direction in an apparatus body. When the upper toner container becomes empty, the replenishment control unit controls the toner replenishing unit so as to replenish the developing device with the toner from the lower toner container.

Abstract: A developer storage container includes a storage portion, a communication portion, a scooping portion, and a guide portion. The storage portion conveys developer stored therein in a conveying direction along a rotation axis by being rotated around the rotation axis in a specific direction. The communication portion connects the storage portion to an opening portion facing the conveying direction. The scooping portion includes a scooping surface facing the specific direction at an end of the storage portion on a downstream side in the conveying direction and radially outside the communication portion to scoop up the developer in contact with the scooping surface as the storage portion rotates. The guide portion lies radially inside the scooping portion to be contiguous with the scooping surface and an inner peripheral surface of the communication portion, and guides the developer scooped up by the scooping portion to the communication portion.

Abstract: An image forming apparatus includes a cassette attachment part and a collection side attachment part. To the cassette attachment part, a sheet feeding cassette storing a sheet is detachably attached. The collection side attachment part is disposed adjacent to the cassette attachment part. To the collection side attachment part, a collection container storing a waste toner discharged without transferred on the sheet is detachably attached. The cassette attachment part includes a cassette rail which supports the sheet feeding cassette slidably and a rail holding member which holds the cassette rail. The collection side attachment part includes a displacement sensor which is disposed so as to face the collection container and detects an electrostatic capacity varying in response to an accumulation amount of the waste toner stored in the collection container. The rail holding member is disposed so as to face at least a part of the displacement sensor.

Abstract: An image forming apparatus includes an apparatus body, an image carrier, a developing device, a toner container, a container cover, a driver and a lock mechanism. The lock mechanism maintains the locking state if the container body is rotated in the first rotating direction by the driver, and receives a rotational drive force of the driver to switch the state thereof from the locking state to the unlocking state if the container body is rotated in the second rotating direction by the driver.

Abstract: A rotation detection device includes a light emitting portion, a light-passing control member, and a light receiving portion. The light-passing control member controls passing of the light from the light emitting portion. The light receiving portion outputs a light receiving signal based on the light received by the respective light receiving elements as detection signals representing detection results of the rotation by the rotator. A first virtual extended line that extends the first opening margin and a light-receiving-portion center line along the first direction passing through the respective light receiving elements at the light receiving portion pass through positions shifted from a rotational center of the light-passing control member. The light receiving portion is arranged such that the first virtual extended line corresponds to the light-receiving-portion center line, when the first opening margin passes through an optical path from the light emitting portion to the light receiving portion.

Abstract: An image forming apparatus includes a storage portion, a cover member, a locking mechanism, an unlocking portion, and a contact portion. The storage portion conveys developer stored therein in a conveying direction parallel to a rotation axis by being rotated around the rotation axis parallel to a horizontal plane in a first direction. The cover member opens and closes an insertion hole portion, into which the storage portion is inserted, in a side face of the apparatus body. The locking mechanism imposes a restriction on a state change of the cover member from a closed state to an open state. The unlocking portion removes the restriction on the state change imposed by the locking mechanism as a lever portion swings in a second direction opposite the first direction. The contact portion includes a curved surface and rotates integrally with the storage portion to come into contact with the lever portion.

Abstract: A container attachment device includes a toner container, an attached part for the toner container and a displacement sensor. The displacement sensor faces to the toner container to detect electrostatic capacity according to the toner. The attached part includes a cover opening/closing an opening of the toner container. The cover closing or opening the opening faces to the displacement sensor, and the cover opening or closing the opening is away from the displacement sensor. The displacement sensor detects the electrostatic capacity varying among a first condition opening the cover and detaching the toner container, a second condition closing the cover and detaching the toner container, a third condition opening the cover and attaching the toner container, and a fourth condition closing the cover and attaching the toner container. In the third or fourth condition, the displacement sensor detects the electrostatic capacity according to a toner quantity in the toner container.

Abstract: An image forming apparatus includes an apparatus body, an image carrier, a developing device, a toner container, a container cover, a driver, a lock mechanism and a lock restricting portion. The lock mechanism is switched to a locking state for locking the container cover in a closed state and an unlocking state for causing the container cover to transition from the closed state to the open state. The lock restricting portion obstructs a state change of the lock mechanism from the unlocking state to the locking state if the container cover is not attached to the apparatus body.

Abstract: A drive transmission unit provided in an image forming device includes a first drive transmission portion and a second drive transmission portion. The first drive transmission portion transmits a rotation drive force of a motor rotating in a first rotation direction to a toner container, to transport a toner housed in the toner container in a predetermined direction, and regulates transmission of a rotation drive force of the motor rotating in a second rotation direction to the toner container. The second drive transmission portion transmits the rotation drive force of the motor rotating in the second rotation direction to the container cover, to cause the container cover to switch from a closed state to an open state, and regulates transmission of the rotation drive force of the motor rotating in the first rotation direction to the container cover.
