Abstract
A photosensitive medium for electrophotography comprises an electricaly conductive or a dielectric substrate, a photoconductive layer overlying the substrate, and a transparent dielectric layer overlying the photoconductive layer. The substrate has the entire peripheral portion thereof formed to provide a region uncovered by the photoconductive layer. The transparent dielectric layer is resistant to liquid developer used in electrophotography and may cover the photoconductive layer and the uncovered region of the substrate. Alternatively, the transparent dielectric layer may be secured to the photoconductive layer and the uncovered region of the substrate by the use of an adhesive which is also resistant to the liquid developer.
