Electrophotographic plate with multiple layers

摘要

An electronic photograph photosensitive plate composed of a high resistant semiconductor layer placed on a conductive base plate and forming a high commutating barrier to check electric charge against coming in from said base plate side, a thin layer consisting of a panchromatic photoconductor in low resistance and high sensitivity placed on said layer to absorb light rays and generate charge carriers, and a transparent high resistant semiconductor layer placed further thereon to hold electric charge and serve as a passage for charge carriers generated.
