Patent ID: 8095036

Claim:
A process cartridge comprising: a first unit including an electrophotographic photosensitive member; a second unit including a developing roller contactable to the electrophotographic photosensitive member for developing an electrostatic latent image formed on said electrophotographic photosensitive member, said second unit being swingable about a swing shaft with respect to said first unit; an urging member for exerting an urging force between said first unit and said second unit so as to contact the developing roller to the electrophotographic photosensitive member; a developing device space keeping member for keeping a space between the developing roller and said electrophotographic photosensitive member; and a protective cover, detachably mountable to at least one of said first unit and said second unit, including a protective portion for protecting said electrophotographic photosensitive member and including a projection which is insertable into a gap between said first unit and said second unit so as to prevent contact between said electrophotographic photosensitive member and said developing roller and which is non-contactable to said first unit and said second unit in a developing device space keeping state by said developing device space keeping member.
