Abstract

PURPOSE: To enable remarkable reduction of imaging time, by imagewise exposing a photoreceptor with a precharged toner ribbon superposed between the photoreceptor and an opposite electrode.
CONSTITUTION: Light projected from the side of transparent electrode layer 3 is absorbed near the electrode side of photoconductive layer 4, and the irradiated part of layer 4 is made conductive. Charge on layer 3 induced by voltage applied between layer 3 and opposite electrode 6 moves to the border face between layer 4 and support tape 8a of toner ribbon 8 only at the irradiated positions, a strong electric field is produced across tape 8a and toner layer 8b between said charge and charge 20 on the surface of layer 8b, and since the area of this dot is small, discharge begins between them. Once discharge begins, the current continues until charge 20 on layer 8b is neutralized with the charge moving through layers 3 and 4, and the discharge current is stopped by peeling of layer 4 from ribbon 8.
