Abstract
An electrophotographic photoreceptor includes an electrically conductive support, a photosensitive layer formed on the electrically conductive support and a surface layer formed on the photosensitive layer. The surface layer contains a resin produced by polymerizing a cross-linkable polymerizable compound, N-type semiconductor fine particles and P-type semiconductor fine particles.
Claims11
An electrophotographic photoreceptor comprising an electrically conductive support, a photosensitive layer formed on the electrically conductive support and a surface layer formed on the photosensitive layer,
- wherein the surface layer contains a resin produced by polymerizing a cross-linkable polymerizable compound, N-type semiconductor fine particles and P-type semiconductor fine particles, and
- wherein in the surface layer, a mass ratio of the P-type semiconductor fine particles to the N-type semiconductor fine particles (part by mass of the P-type semiconductor fine particles/part by mass of the N-type semiconductor fine particles) is within a range of 0.1 to 0.8.
