摘要： A toner case includes a case main body, a rotator, a transmitter and a shutter. The case main body has a discharge port through which a toner is discharged. The rotator is stored in the case main body and rotates around a rotation axis. The transmitter transmits rotation to the rotator. At least a part of the transmitter is exposed to an outside of the case main body. The shutter is rotatable between a closing position where the shutter closes the discharge port and an opening position where the shutter opens the discharge port. The transmitter is movable between a first position and a second position which is arranged at an outside of the first position in a rotation axis direction of the rotator. The transmitter moves from the first position to the second position as the shutter rotates from the closing position to the opening position.

摘要： A toner container includes a container main body, a cylindrical portion, an opening/closing member, and a conveyance member. Container main body includes a storing chamber. Opening/closing member is provided in a inner space of cylindrical portion and, operates to open and close a toner discharge outlet of cylindrical portion. Conveyance member includes rotation shaft and blades along rotation shaft and when rotated, allows blades to convey the toner that is present inside storing chamber and the inner space toward toner discharge outlet. The plurality of blades include a first blade and a second blade. First blade is disposed in storing chamber at a position near a boundary between storing chamber and the inner space and is larger in outer diameter than the other blades. Second blade is disposed in the inner space and is larger than first blade in inclination angle with respect to rotation shaft of conveyance member.

摘要： A developing device includes a development casing, a developer carrying member, a regulating blade, a pair of pressing members, and a blade seal member. The development casing has an opening part. The developer carrying member has a developing area. The blade seal member includes a first layer material and a second layer material. The development casing has facing surfaces. The second layer material has positioning protrusions protruding from the first layer material in a rotation axis direction at positions inside both ends of the first layer material in the rotation axis direction, so as to contact the facing surfaces and be positioned in the rotation axis direction. When the second layer material is positioned in the rotation axis direction, the first layer material is pressed in contact with the pressing members in the rotation axis direction.

摘要： A developing device includes a developing container, a developer carrier, a seal member, and a pair of pressing members. The developing container has an opening. The seal member includes a contact end part, a first blocking part, and an interposed end part. Each of the pressing members has a pressing surface in which a cutout recess is formed. The developing container includes a second blocking part that is adjacent to each end part of the first blocking part in a rotary shaft direction and protrudes upward. The interposed end part is located at such a position as to overlap the cutout recess with respect to a circumferential direction, and the second blocking part is located at such a position as to overlap the cutout recess with respect to the rotary shaft direction.

摘要： Provided is an image forming apparatus including an apparatus main body, an operation member, a toner container, a shutter, and an interlocking mechanism. The operation member is a member for turning on and off a power supply of the apparatus main body, and takes an ON posture and an OFF posture. The toner container is a container configured to store the toner and including an opening section configured to allow communication between the inside and the outside of the container. The shutter can take an opening posture for opening the opening section and a closing posture for closing the opening section. The interlocking mechanism interlocks the posture of the operation member and the posture of the shutter to set the shutter in the opening posture when the operation member takes the ON posture and to set the shutter in the closing posture when the operation member takes the OFF posture.

摘要： A developing device includes a development casing, a developer carrying member, and a regulating blade. The development casing has an opening part. The developer carrying member has a developing area. The development casing has a blade facing part. The regulating blade includes a fixed part and a regulating part, and a space between the regulating part and the blade facing part is larger than a space between the fixed part and the blade facing part. The developing device further includes a blade seal member. The blade seal member is disposed between the regulating blade and the blade facing part, and is glued to an upstream side surface of the regulating part in the rotation direction, so as to seal a gap between the regulating blade and the blade facing part.

摘要： An image forming apparatus includes a toner case and an attachment part. The toner case includes a discharge shutter movable between a first closing position where a discharge port is closed and a first opening position where the discharge port is opened. The attachment part includes a replenishment shutter movable between a second closing position where a replenishment port is closed and a second opening position where the replenishment port is opened. As the discharge shutter moves from the first closing position to the first opening position, the discharge shutter presses the replenishment shutter to move the replenishment shutter from the second closing position to the second opening position. As the discharge shutter moves from the first opening position to the first closing position, the discharge shutter presses the replenishment shutter to move the replenishment shutter from the second opening position to the second closing position.
