PURPOSE:To improve rectifying efficiency and adhesion of an interlayer formed on a conductive substrate, by dispersing at least one of partially oxidized Al powder, Sn powder, and SnO2 powder into a resin binder to form the interlayer. CONSTITUTION:The metallic powder to be used is oxidized only on the surface layer of the dispersed aluminum or the like powder, with oxidation not proceeding into the inner parts. This powder is dispersed into a soln. of a binder of polyester or the like resin. The dispersion is uniformly coated on a stainless steel support purified by washing and dried to form an interlayer. A photoconductive insulating layer is formed on this layer by vacuum metallizing of Se to obtain an electrophotographic receptor. The oxides is produced on the surface of the conductive substrate, and has rectification function, preventing injection of carriers into the photoconductive insulating layer from the substrate side. Adhesion of the interlayer is raised by virtue of the binder resin to improve durability and printing resistance of the photoreceptor. |
