PURPOSE:To reduce leak current and to raise surface potential of a photoreceptor, by combining a photosensitive layer made of amorphous silicon (a-Si) together with a silicon nitride layer and laminating on a substrate in an electrophotographic receptor. CONSTITUTION:A conductive substrate, such as metallic plate or plastic film treated to enhance conductivity, is maintained at 200-300 deg.C, an a-Si layer is formed on the substrate by a glow discharge method, and a silicon nitride layer having 1-1,000nm thickness is formed on said layer to obtain an electrophotographic receptor. Said silicon nitride layer may be formed between the substrate and the a-Si layer, or it may be formed on both sides of the a-Si layer. |
