Abstract
An image forming apparatus has a device for sequentially forming a plurality of images by repeatedly performing an optical writing operation a plurality of times on a photosensitive body face every predetermined timing; a device for sequentially overlapping and transferring the images; a detector for detecting a timing shift from a time point of a command for starting the optical writing operation each time to a start time point of the actual writing operation; and a device for correcting the timing shift to overlap and transfer the images.
