Abstract
An image forming apparatus includes at least an electrophotographic photoreceptor having at least a conductive support, an undercoat layer, and a photosensitive layer; a charging device that charges the surface of the electrophotographic photoreceptor in a contact charging mode, in which only DC voltage is applied; an electrostatic latent image forming device that exposes the surface of the charged electrophotographic photoreceptor to form an electrostatic latent image; a developing device that develops the electrostatic latent image by a developer to form a toner image; and a transfer device that directly transfers the toner image from the electrophotographic photoreceptor to a transfer medium; and does not include an erasing device for erasing the surface of the electrophotographic photoreceptor after the toner image is transferred onto the transfer medium by the transfer device and before the surface of the electrophotographic photoreceptor is charged by the charging device.
