TRIPHENYLAMINE DERIVATIVE AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MATERIAL BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photosensitive material excellent in sensitivity characteristics by using an electric charge-transporting agent excellent in solubility with an organic solvent and compatibility with a binder resin used for the formation of a photosensitive layer. SOLUTION: This electrophotographic photosensitive material comprises the photosensitive layer at least containing an electric charge-generating agent and the electric charge-transporting agent, wherein the electric charge-transporting agent consists of a new triphenylamine derivative expressed by general formula (1) [wherein, Raand R1to R12, and also n1, n2 are each specially defined].
