Abstract
Disclosed is an electrophotogaphic photoreceptor that causes little or no abrasion-derived uneven image density and does not cause scratches and image defects attributable to the occurrence of scratches even after a large volume, for example, exceeding 1,000,000 sheets of printing, and that does not cause image blurring even after printing in an environment of a high-temperature and a high-relative humidity (RH) respectively exceeding 30° C. and 80%. The electrophotographic photoreceptor comprises an electroconductive support and at least a photosensitive layer and a surface layer provided on the electroconductive support and is characterized in that the surface layer contains at least a compound obtained by reacting a polymerizable compound containing a methacryl group with particles containing a functional group reactive with the methacryl group and, in the polymerizable compound, the ratio between the number of methacryl groups and the molecular weight (number of methacryl groups/molecular weight) is not less than 0.0055.
