ABSTRACT OF THE DISCLOSURE Electrophotographic photosensitive element using zinc oxide in a photosensitive layer thereof formed in conductive support are described. Zinc oxide is used in combination with polycarbonate binder and a compound of the specific type. The compound is represented by the formula Image in which R1, R2, R3 and R4 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a cycloalkyl group, an alkenyl group, or an aryl group, R5 and R6 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, or an aryl group, R7, R8, R9 and R10 independently represent a hydrogen atom, a hydroxyl group, a substituted or unsubstituted alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an alkoxy group or an amino group. Optionally, R5 and R6 may jointly form a saturated or unsaturated hydrocarbon ring having from 3 to 10 carbon atoms.
