Abstract: In a case where a developer bottle is not attached to a bottle attachment portion, a movable support portion is kept to be at a support position, by an elastic force of a second spring, at which to support the bottle attachment portion to be higher than a reference level in position. In a case where the developer bottle is attached to the bottle attachment portion, a movable arm portion extending from the movable support portion toward an attachment space contacts the developer bottle and is displaced to outside the attachment space, which causes the movable support portion to be displaced from the support position to a release position at which to release a support of the bottle attachment portion. A control portion prohibits an image forming process when the position of the bottle attachment portion is not equal to or lower than the reference level.

Abstract: A developer storage container includes: a container body which includes an opening portion opened toward a conveying direction along a rotation shaft and is rotated in a specific direction about the rotation shaft to convey toner stored therein in the conveying direction and discharge the toner from the opening portion; a cap portion which downwardly guides the toner discharged from the opening portion at a position more on a downstream side of the conveying direction than the opening portion; and an extension portion which is formed integrally with the container body and extends from inside the container body toward the downstream side of the conveying direction beyond the opening 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 developer storage container includes a storage portion, a communication portion, and a gear portion. The storage portion conveys developer stored therein in a conveying direction parallel to a rotation axis by being rotated around the rotation axis in a specific direction. The communication portion has a tubular shape coaxial to the rotation axis and extending in the conveying direction from an end of the storage portion on a downstream side in the conveying direction, includes an inner peripheral part that gradually increases its diameter in the conveying direction, and connects the storage portion to an opening portion that has an opening facing the conveying direction. The gear portion is provided for an outer peripheral part of the communication portion and receives a rotational driving force supplied from the outside.

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 in the specific direction. 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.

The communication portion is tubular coaxial to the rotation axis and extending in the conveying direction from a downstream end in the conveying direction, and connects the storage portion to an opening portion facing the conveying direction. The gear portion includes a disc-shaped support portion provided for an outer peripheral part of the communication portion concentrically with the rotation axis, a tooth portion along an edge of a support surface, orthogonal to the rotation axis, of the support portion, and a rib extending on the support surface radially from the tooth portion or the outer peripheral part without reaching the other; and receives rotational driving force supplied from outside.

Abstract: A cushion member includes a tubular portion and an abutting portion. The tubular portion has, in its inside, a hollow that extends in a second direction perpendicular to a first direction that is a longitudinal direction of a storage portion. The tubular portion can be elastically deformed by an external force in the first direction. The abutting portion abuts on, in the first direction, a portion of the cover portion other than the lid. An evasive cut portion is formed at a portion of the tubular portion that faces the lid of the cover portion in the first direction, the evasive cut portion being a cut that is cut into from an end of the tubular portion in the second direction.

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.
