Abstract
Improved organophotoreceptor have an electrically conductive substrate, a charge generation layer comprising a charge generation compound and optionally a charge transport compound, and an overcoat layer comprising an electron transport compound wherein the charge generation layer is between the overcoat layer and the electrically conductive substrate. The organophotoreceptor can optionally comprise a charge transport layer and/or other desired layers. The organophotoreceptors are useful in electrophotographic imaging apparatuses and corresponding processes.
