摘要： 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.

摘要： 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.
