ABSTRACT:
A method of improving the reusability, in a liquid electrophoretic development process, of an electrophotographic photosensitive plate which has, in the following recited order, a base which is a conducting substrate, a thin vitreous sensitizing layer including selenium, and an organic carrier transporting layer which is polyvinylcarbazole or a polyvinylcarbazole derivative with at least one inactive additive. The main feature of the method is to apply, by glow discharge in a vacuum chamber, a top organic film on the surface of the organic carrier transporting layer.
