Abstract
An electrophotographic photoreceptor comprises an electrically conductive support, a photoconductive layer provided thereon, and a protective layer coated on the photoconductive layer, wherein the protective layer comprises a product of uncatalized hydrolysis of a composition essentially consisting of at least one specific epoxysilane compound, at least one specific alkylalkoxysilane compound, and at least one specific aminosilane compound. The photoreceptor is very useful in that it is free from wear due to friction with paper and cleaning members, keeps high resolving power, and is sufficiently proof against continuous copying under conditions of high temperature and high humidity.
