Abstract:
1. A color electrophotographic image forming apparatus comprising: a photosensitive member cartridge, detachably mountable to a main assembly of said color electrophotographic image forming apparatus, for holding a photosensitive member; a plurality of developing cartridges each including a developing roller for developing an electrostatic latent image formed on said photosensitive member into a developer image, said plurality of developing cartridges being demountable from said photosensitive member cartridge; a main assembly-side guide portion, provided in the main assembly, for guiding said photosensitive member cartridge demountably from the main assembly; a photosensitive member cartridge-side guide portion, provided in said photosensitive member cartridge, for guiding said plurality of developing cartridges independently demountably from said photosensitive member cartridge; a preventing portion, provided in said photosensitive member cartridge, for preventing movement of said photosensitive member cartridge, and a grip portion for permitting demounting of said photosensitive member cartridge, said grip portion being operable so as to change a position of said preventing portion from a first position to a second position, wherein, when an operation for demounting said developing cartridges is performed in a state in which said photosensitive member cartridge is mounted in the main assembly, said preventing portion is movable between the first position in which said photosensitive member cartridge is prevented from moving in a demounting direction in which said photosensitive member cartridge is to be demounted and the second position in which said photosensitive member cartridge is permitted to move in the demounting direction.
