PURPOSE:To obtain an electrophotographic sensitive body capable of forming a sharp image by laminating on a conductive substrate an electric charge generating layer, a charge transfer layer, and moreover, a charge generating layer to form a photoconductive layer and a dielectric layer on the surface. CONSTITUTION:The organic electrophotographic sensitive body 7 is formed by laminating on the conductive substrate drum 1 the transparent conductive layer 2, the first charge generating layer 3, the charge transfer layer 4, the second charge generating layer 5, and the dielectric layer 6. Carriers, reverse in polarity to charge, generated in the layer 3 by exposure to light, transferred, and held in the interface between the layer 6 and the layer 5. Next, carriers same in polarity as the charge and same in amount as the charge held in the interface is transferred from the layer 5 toward the layer 6 by overall exposure to erase the charge held in the interface, thus permitting positive carriers to be transferred in both directions, the charge held in the interface between the layers 5 and 6 to be perfectly erased, and unsharpness of an image due to residual potential to be avoided. |
