Abstract:
An electrophotographic photoreceptor comprising:an electroconductive substrate; an interlayer formed on the substrate; and a photosensitive layer formed on the interlayer, wherein the interlayer comprises fine metal oxide particles and a binder resin; wherein the interlayer has a volume resistivity in a range of from 108 to 1013 &OHgr;Â·cm, when electric field of 106 V/m is applied thereto at 28Â° C. and 85% RH; wherein the volume resistivity of the interlayer at a time when an electric field of 106 V/m is applied thereto at 15Â° C. and 15% RH is not higher than 500 times of the volume resistivity thereof at a time when an electric field of 106 V/m is applied thereto at 28Â° C. and 85% RH.
