ABSTRACT:
An image forming apparatus wherein a latent image is formed on an image bearing member, corresponding to the image information to be recorded by the charging and exposure steps effected to the image bearing member. The latent image is developed, and the developed image is transferred onto a transfer material. The developing device is movable between its operative position where it is capable of developing the latent image on the image bearing member and its inoperative position where the developing device is retracted from the operative position. A control device is provided to effect the movement of the developing device between the operative position and the inoperative position at other than the image exposure step or not during the transfer step.
