Abstract
A color electrophotographic image forming apparatus includes: a drum cartridge, detachably mountable to the apparatus main assembly, for holding a drum; developing cartridges, each including a developing roller for developing an electrostatic latent image formed on the drum, demountable from the cartridge; a main assembly guide for guiding the cartridge from the main assembly; a drum cartridge guide for guiding the developing devices independently demountably from the cartridge; and a drum cartridge preventor for preventing movement of the cartridge. When the developing cartridge is demounted while drum cartridge is mounted in the main assembly, the preventor is movable between a first position preventing the cartridge from moving in a demounting direction and a second position permitting such movement. The apparatus includes a grip for facilitating demounting of the drum cartridge by facilitating a change of the preventor's position from the first position to the second position.
