Abstract
An electrophotographic photoreceptor having, between an electroconductive substrate and a photosensitive layer, an interlayer which contains fine metal oxide particles and a binder resin and which, when an electric field of 106 V/m is applied thereto at 28° C. and 85% RH, has a volume resistivity of from 108 to 1013 &OHgr;·cm and, when an electric field of 106 V/m is applied thereto at 15° C. and 15% RH, has a volume resistivity which is up to 500 times the volume resistivity thereof as measured when an electric field of 106 V/m is applied thereto at 28° C. and 85% RH.
