PURPOSE:To obtain the excellent suitability for image formation in which coherent monochromatic light is used and to permit easy production control by providing a photoreceptive layer made into multi-layered structure on a base having a specific surface characteristic and incorporating at least one kind of O, C or N atoms into the photoreceptive layer. CONSTITUTION:The photoreceptive layer 1000 made into the laminated structure in which the 1st layer 1002 contg. a-SiGe and the 2nd layer 1003 contg. a-Si and a surface layer 1006 consisting of an amorphous material contg. Si and C are successively laminat ed is disposed on the base 1001 formed with many projecting parts having the sectional shape superposed with auxiliary peaks on main peaks in the prescribed cutting position. One kind of O, C or N atoms is incorporated into the layer 1000. The electrical characteristics are stabilized and the high sensitivity and high SN ratio are obtd. without the influence of residual potential on image formation when such photoreceptive member is used for electrophotography. The photoreceptive member has excellent resistance to photo-fatigue and repetitive use characteristic and yields stably and repeatedly the sharp image having high image quality. Said member has the high photosensitivity over the entire visible region, has good matching with a semiconductor laser and has excellent mechanical durability on the surface. |
