To provide a process cartridge capable of forming a high-quality image even after the lapse of storage time by restraining the deterioration of the characteristic of a photoreceptor caused by the repetition of electrification exposure after the lapse of storage time.

In the process cartridge where an electrophotographic photoreceptor equipped with a conductive supporting body and a photoreceptive layer and containing lubricant in the surface layer of the photoreceptive layer, and at least one means selected from a group consisting of an electrifying means, a developing means and a cleaning means are integrally supported in a frame body, and which is freely attached to/detached from an electrophotographic device, the frame body is composed of resin containing an antioxidant, and the antioxidant is migrated from the frame body to the electrophotographic photoreceptor.
