Abstract

PURPOSE: To enhance the adherence between an electrically conductive support and a photosensitive layer; raise the gradation of an image; and prevent formation of white specks by interposing a middle layer containing ammonia-treated casein between the support and the layer.
CONSTITUTION: Casein is swollen with water, and ammonia water is added to the swollen casein, heat treated at 70°C, and filtered to prepare a coating solution. This solution is coated onto an electrically conductive support in a rate of 2W6g/m2 as casein. After drying on the casein layer a photosensitive layer of an inorganic photoconductive substance such as Se or a high-molecular organic photoconductive substance such as polyvinyl carbazole is formed. The resulting photoreceptor withstands repeated copying and provides a clear image.
