ABSTRACT:
The object of the invention is to reduce the number of parts which are required for supporting a photosensitive drum in a photosensitive drum cartridge. Engaging bodies of supporting members are inserted through mounting holes of a cartridge main body. Supporting shafts are inserted into supporting shaft insertion holes formed on the sides of a photosensitive drum. When the supporting members are rotated, the side walls of the cartridge main body are fitted into gaps between flat plates and engaging pieces. The supporting members are positioned with respect to and fixed to the cartridge main body, whereby the photosensitive drum is supported in the cartridge main body.
