1. A photosensitive member for use in electrophotography comprising:
- an electroconductive substrate;
a photosensitive layer comprising a photoconductive material on said substrate;
said photosensitive layer comprising a mixture of a binder of a self-hardening type resin and a finely divided powder of a photoconductive material;
said photosensitive layer having a mirror finish with a surface irregularity of less than 0.1 μ

Abstract
A photosensitive member for use in electrophotography in manufactured by preparing a coating material by mixing together a powder of photosensitive material, for example α or ε phthalocyanine, and a binder of a self-hardening type resin, for example a polyester resin, applying the coating material on the surface of a hollow metal cylinder to form a photosensitive layer, smoothing the surface of the photosensitive layer by applying a mechanical force, and hardening the photosensitive layer by heat or ultraviolet ray.

10. A method of manufacturing a photosensitive member for use in electrophotography, comprising the steps of:
-
preparing a coating material by mixing together a powder of photoconductive material and a binder of a self-hardening type resin; applying said coating material onto a surface of an electroconductive substrate to form a photosensitive layer; hardening said photosensitive layer; and thereafter mechanically smoothing said photosensitive layer to a mirror finish having a surface irregularity of less than 0.1 μ
