Abstract

A xerographic photoreceptor primarily formed by amorphous silicon material is disclosed, wherein the xerographic photoreccptor is a photosensitive drum used in copying and manufactured by the plasma enhanced low pressure chemical vapor deposition system. Such a drum has a higher resolution, and a longer lifetime. In this structure, an Al.sub.2 O.sub.3 oxidization layer is grown on an aluminum substrate. Then a n type hydrogenated amorphous silicon blocking layer is grown on the aluminum substrate with Al.sub.2 O.sub.3 oxidization layer. Then an intrinsic hydrogenated amorphous silicon charge generating transmission layer is grown on the n type hydrogenated amorphous silicon blocking layer. Finally a hydrogenated amorphous carbon surface protecting layer is grown on the intrinsic hydrogenated amorphous silicon charge generation transport layer for forming a xerographic photoreceptor with a multiple layer structure. Not only the manufacturing process is simple, but also a lager area is achieved in preparing a film manufacture and thus, the cost will be reduced.
