<p>A color image forming apparatus in which at least one registration mark (1a, 1b) is formed on a movable image retainer, and exposed by an exposing device (120, 220, 320, 420). A position of the registration mark (1a, 1b) is detected by a detecting device (FS1 - FS8, 52, 53) incorporating with said exposing device (120, 220, 320, 420) to generate a signal based on the detected position of the registration mark (1a, 1b). An exposing position of the exposing device (120, 220, 320, 420) is corrected by a correcting device (500, 550) in accordance with the signal to form a latent image on the image retainer (1). <IMAGE></p> |
