Abstract
When a space holding member for holding a photosensitive drum and a developing roller in a spaced-apart state act on a process cartridge main body, the photosensitive drum and the developing roller are held in the spaced-apart state, and when the holding member is acting on a process cartridge, a storing medium provided in the process cartridge and the communication member of the storing medium are covered and hidden by the holding member. By the above-described construction, the spacing-apart of the developing roller and the protection of the storing medium can be effected by a member, and an improvement in usability and the curtailment of the number of parts can be achieved.
