The present invention provides a photosensitive material for use in electrophotography which comprises a conductive support having a photoconductive layer coated with a protective layer, the material being superior in light-decay property, mechanical strength and image formability, wherein said protective layer is composed of either (1) a member selected from the group of resins consisting of polyvinyl butyral, polyvinyl acetate, acryl or derivative resins thereof, copolymers of styrene and maleic anhydride or alkyl esters thereof, copolymers of vinyl acetate or derivatives thereof and vinyl pyrrolidone, copolymers of butyl vinyl ether and maleic anhydride or alkyl monoesters thereof and shellac, or of (2) a resin and silane-coupling agent.
A photosensitive material for use in electrophotography comprising an electrically conductive support having a photoconductive layer overcoated thereon with a protective layer wherein said protective layer is composed of a film forming, transparent resin and, based on the total weight of the protective layer, from about 0.01 wt.% to 10 wt.% of a silane-coupling agent.
