Abstract
An image forming apparatus comprising (a) a photoreceptor comprising an endless transparent support having thereon a transparent conductive layer, a charge carrier generation layer and a charge carrier transport layer; (b) a charger for charging uniformly the outermost surface of the photoreceptor; (c) an exposing means for having the photoreceptor exposed to light from the side of the support to form an electrostatic latent image on the surface of the photoreceptor; (d) a developing means for developing the electrostatic latent image to form a toner image; (e) a transfer means for transferring the toner image onto a transfer material; and (f) a fixing means for fixing the toner image transferred, wherein a transmittance of the charge carrier generation layer is 20% or less with respect to exposing light emitted from the exposing means, and a carrier drift mobility in the charge carrier transport layer is 1.times.10.sup.-6 cm.sup.2 /V.sec or more under an electric field intensity of 2.times.10.sup.5 V/cm.
