TRIARYLAMINE HYDRAZONE DERIVATIVE AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor excellent in sensitivity characteristics by using an electron-transporting agent excellent in dissolvability with organic solvents and compatibility with a binder resin used for forming the photosensitive layer. SOLUTION: This electrophotographic photoreceptor equipped with the photosensitive layer containing at least an electric charge-generating agent and the electron-transporting agent is provided with that the electron-transporting agent consists of a new triarylamine hydrazone derivative expressed by general formula (1) [wherein, R is a≥6C linear alkyl; R1is H, a 1-6C alkyl, a 1-6C alkoxy, phenoxy, a 6-20C aralkyl or a 6-20C aryl, wherein, the alkyl, aralkyl or aryl group may have a substituent; and (n) is an integer of 1 or 2].
