Abstract
An electrophotographic photoreceptor comprises a photoconductive layer having a protective layer disposed thereon, said protective layer being formed by dehydrocondensation of the hydrolyzate of a perfluoroalkyl silane coupling agent, or the hydrolyzate of a mixture of a perfluoroalkyl silane coupling agent and a silane coupling agent. The photoreceptor is very useful in that it can exhibit a high performance even in an environment at a higher temperature and at a higher humidity and that it has a high resistance to the abrasion with a great number of sheets being printed and with the cleaning members and that it is capable of preserving a high resolution without any image blurring.
