Abstract
A cartridge unit includes a first drum cartridge, a first cover member, a stopper, and a first cover erroneous insertion blocking portion. The first cover member is removably attached with the first drum cartridge and configured to be compatible in shape with a first holding portion of a first apparatus body so that the first cover member is guided and held by the first holding portion. The first cover erroneous insertion blocking portion is configured to permit the first cover member to be guided by the first holding portion by a first distance from a first insertion slot portion and to block a second cover member, which is removably attached with a second drum cartridge functionally different from the first drum cartridge, to be guided by the first holding portion in a range exceeding a second distance shorter than the first distance from the first insertion slot portion.
