Electrophotographic color image forming apparatus

A color electrophotographic image forming apparatus for forming a color image on a recording material, the apparatus comprising:

• a supporting member capable of supporting a plurality of electrophotographic photosensitive drums and being movable between i) an image forming position which is inside a main assembly of the apparatus and at which electrostatic latent images are formable on the electrophotographic photosensitive drums, respectively, and ii) a retracted position which is inside the main assembly of the apparatus and which is retracted from the image forming position;
• driving means for driving the electrophotographic photosensitive drums;
• a recording material feeding belt for electrostatically attracting and feeding the recording material onto which the images formed by developing the electrostatic latent images formed on the electrophotographic photosensitive drums are transferred;
• and
• a controller for controlling execution of image formation so as to provide, on the electrophotographic photosensitive drums, areas having a lowered absolute value of surface potential, and so as to stop driving of the electrophotographic photosensitive drums by the driving means in a state that the areas are opposed to the recording material feeding belt.
