SINGLE-LAYERED ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PURPOSE: A single-layered electrophotographic photoreceptor is provided, to reduce the residual potential in high sensitivity and to prevent the deterioration of potential decrease velocity in a low wave filed region. CONSTITUTION: The single-layered electrophotographic photoreceptor comprises a photosensitive layer containing at least a charge generation material, a hole transport material and an electron transport material on a conductive supporter, wherein the photosensitive layer contains a charge transport complex formed by a hole transport material represented by the formula 1 and an electron transport material represented by the formula 2. In the formula 1, R1 to R5 are independently H, a substituted or unsubstituted alkyl group of C1-C20, a substituted or unsubstituted aryl group of C6-C20, a substituted or unsubstituted alkoxy group of C1-C20 or a substituted or unsubstituted styryl group of C8-C20; and in the formula 2, A and B are independently H, a halogen atom, an alkoxycarbonyl group of C2-C20 or an alkylaminocarbonyl group of C2-C20, and the hydrogen atom of the aromatic ring can be substituted with a halogen atom.
