ABSTRACT:
A method of manufacturing an electrophotographic photoreceptor for use in a copying apparatus or a printer is disclosed. The method comprises steps of providing an electrically conductive substrate, providing a first layer provided on the substrate for preventing injection of electrons into the photoreceptor from the substrate, providing a second layer of amorphous silicon provided on the first layer for determining charging characteristic of photoreceptor and providing a third layer for preventing injection of holes into the photoreceptor from the surface thereof and for effecting passivation of the surface. The second layer is subjected to doping of boron, which is effected by introducing a mixed gas of boron and silicon with a ratio of 0.2-2 ppm into a growth chamber.
