A cartridge includes a drum unit and a development unit. The drum unit includes a photosensitive drum, a frame, a transfer roller, and a cleaning member. The development unit includes a development roller, and a memory. The cleaning member is configured to come into contact with the photosensitive drum at a region between a development nip portion and a transfer nip portion in a circumferential direction of the photosensitive drum and at an end portion of the photosensitive drum in a direction of the rotational axis. The frame has an exposing hole through which the memory is exposed from the frame, and a recessed portion that is adjacent to the exposing hole in the direction of the rotational axis, and stores foreign matters removed from the photosensitive drum by the cleaning member.

Cartridge and image forming apparatus

A process cartridge includes a first unit including an image bearing member configured to carry an electrostatic latent image, and a second unit including a developer bearing member configured to develop the electrostatic latent image carried on the image bearing member into a toner image, the second unit being capable of being mounted on the first unit in a mounting direction. The first unit includes a moving member that moves the second unit mounted on the first unit at a mounting position to a detachment position. The second unit includes a storage unit that stores information about the second unit. The moving member is disposed on a first side of the process cartridge in a longitudinal direction of the image bearing member. An electrode of the storage unit is disposed on a second side of the process cartridge in the longitudinal direction.

Process cartridge and image forming apparatus

A drum unit detachably mountable to a main assembly of an electrophotographic image forming apparatus includes a photosensitive drum and a coupling member provided on the photosensitive drum. The coupling member includes a driving force receiving portion and a supporting portion movably supporting the driving force receiving portion. The supporting portion includes a first extended portion and a second extended portion which extend at least in an axial direction of the photosensitive drum.

Drum unit, cartridge, electrophotographic image forming apparatus and coupling member

A process cartridge mountable in and dismountable from an image forming apparatus includes a frame, a storing portion provided on a mounting surface of the frame and configured to store information on the process cartridge, a projection projecting outwardly of the mounting surface in a direction normal to the mounting surface, and an electrical contact portion mounted on the projection and electrically connected to the storing portion.

Process cartridge and image forming apparatus having an electrical contact portion mounted on a projection and electrically connected to a storing portion

A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes a developer discharging member; a cartridge positioning portion for engagement with a main assembly positioning portion provided in the main assembly when the cartridge is mounted to the main assembly; a photosensitive member driving force receiving portion for receiving a driving force for rotating the photosensitive member from the main assembly when the cartridge is mounted to the main assembly; and a discharging member driving force receiving portion for receiving a driving force for rotating the developer discharging member from the main assembly when the cartridge is mounted to the main assembly. The rotational directions of the photosensitive member driving force receiving portion and the discharging member driving force receiving portion are the same, and the rotation directions are such that a rotation moment is produced so as to contact the cartridge positioning portion to a lower surface of the main assembly positioning portion of the apparatus.
