PURPOSE:To simplify and miniaturize a cartridge structure and reduce cost by constituting a cartridge frame so that a space part to be a waste toner vessel is formed in the opposite side of a blade to a photosensitive drum. CONSTITUTION:A cleaner unit 3 in a photosensitive body cartridge consists of a blade 30 which scrapes a toner remaining on the surface of a photosensitive drum 1, a waste toner vessel 31, a waste toner recovering rotating plate 32 which sends the toner scraped by the blade to the waste toner vessel 31 as a waste toner by rotating, and a partitioning plate 33 which demarcates the waste toner vessel 31. An aperture is formed under the partitioning plate 33, and the waste toner is sent into the waste toner vessel 31 through this aperture part. A space part is formed with a frame 6 in the opposite side of the blade 30 to the photosensitive drum to constitute the waste toner vessel 31. That is, the waste toner vessel 31 is formed directly with inside walls of an upper frame 6a and a lower frame 6b and the partitioning plate 33. |
