ORGANIC PHOTORECEPTOR AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To prevent the lowering of image quality by the enlargement of the exposure diameter of a record image due to moire and multiple reflection. SOLUTION: Regular surface roughness wave-forms are formed on the surface 21 of a substrate 2, fine ruggedness of 0.1-1.5μm height is provided to each of the wave-forms and excess laser light which reaches the surface of the substrate 2 is diffused and scattered in an undercoat layer 3 by the fine ruggedness of 0.1-1.5μm height in every regular surface roughness wave-form of the surface 21 of the substrate 2 to prevent multiple reflection due to the excess laser light which reaches the surface of the substrate 2.
