Abstract
This invention relates to an improved organophotoreceptor that comprises an electrically conductive substrate having at least a surface; an inner photoconductive layer adjacent the surface of the electrically conductive substrate; and an outer photoconductive layer adjacent the inner photoconductive layer. In some embodiments, the inner photoconductive layer comprises a first binder in an amount not more than 45% by weight of the inner photoconductive layer, a first charge generating compound, and a charge transport compound, and the outer photoconductive layer comprises a second binder in an amount not less than 45% by weight of the outer photoconductive layer and a second charge generating compound. The inner photoconductive layer and the outer photoconductive layer can be discrete layers or sections of a gradient layer.
