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.
