Abstract
The invention relates to an electrophotographic photoreceptor in which protrusions from the surface of the photoreceptor are partly or completely covered by a resin. The effect of such resin covering is to reduce toner deposition, thereby reducing or eliminating spotting defects in images formed using the electrophotographic photoreceptor. The invention further relates to an image-forming apparatus incorporating such an electrophotographic photoreceptor.

An electrophotographic photoreceptor comprising:
- an electrically conductive substrate;
- a photosensitive layer comprising an a-Si material formed on the substrate, the photosensitive layer having a protrusion;
- and
- a resin portion partly or entirely covering the protrusion.
A method for manufacturing an electrophotographic photoreceptor, comprising the steps of:
- forming a photosensitive layer comprising an a-Si material on an outer surface of a cylindrical substrate, the photosensitive layer having a protrusion;
- and
- partly or entirely covering the protrusion of the inorganic photosensitive layer with a resin.
An image-forming apparatus comprising an electrophotographic photoreceptor, the electrophotographic photoreceptor comprising:
- a cylindrical substrate;
- an photosensitive layer comprising an a-Si material on the cylindrical substrate, the photosensitive layer having a plurality of protrusion;
- and
- a resin portion partly or entirely covering the protrusion.
