Abstract
An electrophotographic photoreceptor comprising at least a substrate, an electrical charge generating layer, and an electrical charge transporting layer, wherein the electrical charge transporting layer comprises a material selected from the group consisting of an oxide, carbide, and nitride of aluminum, and a mixture of two or more of the foregoing, the selected material being combined with a transition metal element.
Claims19
An electrophtographic photoreceptor comprising:
- a substrate;
- an electrical charge generating layer;
- and
- an electrical charge transporting layer, wherein said electrical charge transporting layer comprises at least one material selected for the group consisting of aluminum oxide, aluminum carbide, and aluminum nitride, said selected material being combined with a transition metal element, said transition metal element being present in a range of 0.01-30 atomic percent;
- wherein when said electrical charge transporting layer comprises aluminum oxide, said charge transporting layer comprises oxygen and aluminum, said oxygen having an atomic a ratio of at least 0.1 with respect to said aluminum;
- wherein when said electrical charge transporting layer comprises aluminum nitride, said charge transporting layer comprises nitrogen and aluminum, said nitrogen having an atomic ratio of at least 0.1 with respect to said aluminum;
- and wherein said said electrical charge transporting layer comprises aluminum carbide, said charge transporting layer comprises carbon and aluminum, said carbon having an atomic ratio of at least 0.05 with respect to said aluminum.
