Patent ID: 7045264

Claim:
A single layered electrophotographic photoreceptor comprising: a photosensitive layer having at least a charge generating material, a hole transporting material, an electron transporting material, and a binder on a conductive support, wherein the photosensitive layer includes a charge transfer complex (CT-complex) formed by the hole transporting material of Formula 1 and the electron transporting material of Formula 2: wherein R1 through R5 are independently selected from the group comprising a hydrogen atom, a C 1 –C 20 optionally substituted alkyl group, a C 6 –C 20 optionally substituted aryl group, a C 1 –C 20 optionally substituted alkoxy group and a C 8 –C 20 optionally substituted styryl group; wherein A and B are independently selected from the group comprising a hydrogen atom, a halogen atom, a C 2 –C 20 optionally substituted alkoxycarbonyl group and a C 2 –C 20 alkylaminocarbonyl group, wherein the hydrogen atom in the aromatic ring is optionally substituted by a halogen atom.
