ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor having high sensitivity in positive charge and excellent in electrical characteristics. SOLUTION: The electrophotographic photoreceptor has a photosensitive layer containing an electron transferring material of formula I or the like. In the formula, R1-R4 are each H, a 1-8C optionally substituted alkyl or alkoxy, an optionally substituted aryl or a residue for forming a ring; R5 and R6 are each H, a 1-8C optionally substituted alkyl or an optionally substituted aryl; and each A1 is 0 or =CR7R8 (R7 and R8 are each cyano or alkoxycarbonyl).
