Abstract: A photosensitive member unit includes photosensitive drums and a frame including positioning portions. One and the other end shaft portions of the photosensitive drums are movable between first positions in which the above-mentioned one and the other end shaft portions are positioned by the positioning portions and second positions in which the above-mentioned one end of the other end shaft portions are not positioned by said positioning portions. The photosensitive member unit includes a plurality of mounting portions which are provided in the frame and to which developing units including developing members capable of supplying toner to the photosensitive drums are mountable, and from which the developing units are dismountable without dismounting the photosensitive drums from the frame, in a state that the above-mentioned one and the other end shaft portions are positioned by the positioning portions.

Abstract: An image forming apparatus includes: a cartridge; a developer container, in which the cartridge allows the developer container to be movable between first and second positions; an apparatus main body including an opening through which the cartridge passes when the cartridge is attached and an opening and closing member movable between an open position to open the opening and a close position to close the opening; and a moving member moving to be at different positions between a case where the developer container is attached at the first position and a case where it is attached at the second position, and when the developer container is attached at the first position, the moving member is at a position of preventing movement from the open position to the close position, and when it is attached at the second position, the moving member is at a position of allowing the movement.

Abstract: A cartridge detachably attached to an apparatus body of an image forming apparatus includes: a restriction member provided on a toner cartridge, the restriction member being movable between a restriction position, at which relative movement between (1) the toner cartridge attached to the attachment portion of the process cartridge and (2) the process cartridge is restricted by an engagement of the restriction member and the process cartridge, and a non-restriction position, at which the relative movement is not restricted; and a driving transmission unit for transmitting a driving force from the apparatus body to the toner cartridge by engaging with the apparatus body. The restriction member moves from the restriction position to the non-restriction position when a driving force reception unit receives the driving force from the driving transmission unit.

Abstract: A cleaning device detachable from an image forming apparatus, the cleaning device including a frame that includes a waste toner containing unit that contains toner removed with a cleaning member, a vent hole that communicates an inside and an outside of the waste toner containing unit and that is covered with a filter, and a partitioning portion that protrudes inside the waste toner containing unit. In a state in which the cleaning device in mounted in the image forming apparatus, there is a contact position where the image bearing member and the cleaning member come in contact with each other, and the partitioning portion is positioned between the vent hole and the contact position in a vertical direction.
