Abstract

An electrophotographic photoreceptor is disclosed which comprises a support having provided thereon a charge generating layer containing silicon as a main component and a charge transport layer containing as a main component an oxide of at least one element selected from aluminum, zirconium, and tantalum, said charge generating layer and charge transport layer being adjacent to each other. The photoreceptor has a charging capacity of about 50 V/.mu.m or more and a rate of dark decay of 15%/sec or less.
