ABSTRACT:
The invention relates to an electrophotographic photosensitive member, and more specifically, to a photosensitive member having a photosensitive layer superimposed over a substrate. In one aspect of the invention, sequential laminations of a dispersion layer of conductive tantalum-doped tin oxide powder dispersed in a binder resin solution, are provided between the substrate layer and the photosensitive layer. Another aspect of the invention relates to a protective layer provided for the photosensitive layer. The protective layer of the most exterior surface of the photosensitive member may be a dispersion layer formed by dispersing tantalum-doped tin oxide powder in a resin solution.
