Abstract
An electrophotographic photoreceptor comprising a conductive support having thereon an amorphous silicon photoconductive layer and a surface protective layer is disclosed, the surface protective layer having a laminated structure comprised of a lower layer comprising nitrogen-containing amorphous silicon and an upper layer comprising amorphous carbon. The photoreceptor causes no image deletion even after repeated use under a high temperature and high humidity condition and exhibits excellent scratch resistance.
