Patent ID: 8417134

Claim:
A color electrophotographic image forming apparatus for forming a color image on a recording material, wherein a plurality of cartridges each including an electrophotographic photosensitive drum are detachably mountable to a main assembly of the apparatus, the apparatus comprising: exposure means for forming an electrostatic latent image on the electrophotographic photosensitive drum; a cartridge supporting member capable of demountably supporting the cartridges and movable between an inside position inside the main assembly of the apparatus and an outside position outside the main assembly of the apparatus; driving means for driving the electrophotographic photosensitive drum; an intermediary transfer belt onto which an image provided by developing the electrostatic latent image formed on the electrophotographic photosensitive drum is transferred; and a controller for controlling execution of image formation in response to print jobs received by the apparatus, wherein said controller causes said exposure means to expose the electrophotographic photosensitive drum to light after completion of a last one of the print jobs, and said controller stops drive of the electrophotographic photosensitive drum by said driving means in a state that the exposed area is opposed to said intermediary transfer belt.
