ABSTRACT:
A light-receiving member, and an electrophotographic apparatus comprising it, which the member comprises a conductive support, a first layer capable of exhibiting a photoconductivity which comprises at least a material of a non-single-crystal silicon type, a second layer comprising silicon atoms and one kind selected from the group consisting of carbon atoms, nitrogen atoms and oxygen atoms, and a third layer comprising silicon atoms and one kind selected from the group consisting of carbon atoms, nitrogen atoms and oxygen atoms, the conductivity type of which has been adjusted to be of the same polarity as charging polarity by incorporating at least one element belonging to the Group III elements of the periodic table, the first, second and third layers being superposingly provided in this order, wherein the light-receiving member is used for positive charging and requires no drum heater, thereby achieving a very good image quality in any environment.
