Abstract

The use of pigmenthinder combinations in charge generator layers (CGL) in various multilayered photoreceptor devices containing a charge generator layer and a charge transport layer (CTL) is well known. In some embodiments, it has been demonstrated that thin CGL layers highly loaded with photoconductive pigment are desirable, but the application techniques for forming coatings from pigment dispersions may constrain the ability to achieve smooth uniform layers. For example, in devices in which a CGL overlies a CTL, application of a thin CGL by spray coating has been shown to create irreducible background in points made on a Xerox 4045 printer.
