Abstract
An image forming apparatus has a device for performing a scanning operation using a laser beam by a polygon mirror at a predetermined timing; a writing device for sequentially forming a plurality of images by repeatedly performing an optical writing operation a plurality of times on a photosensitive body; a transfer device for sequentially overlapping and transferring the plurality of images onto a transferred member; and a device for starting the optical writing operation each time by the writing device from the same polygon mirror face. The photosensitive body is constructed by a photosensitive body belt and the optical writing operation is started from the same polygon mirror face approximately every integral multiple of one rotation of a driving roller for the photosensitive body.
