Electrophotographic photosensitive member

摘要

An electrophotographic photosensitive member which comprises an aluminum substrate having an aluminum oxide film at its surface and a photosensitive layer formed on the substrate, which contains a photoconductive material, wherein the aluminum oxide film has a thickness of from 3 to 15 mu m, and a resistivity of from 109 to 3x1010 OMEGA /3.14 cm2 when a DC voltage of 20 V is applied, and an impedance of from 1 to 20 M OMEGA at 100 Hz.
