TRIPHENYLAMINE DERIVATIVE AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND IMAGE FORMATION EQUIPMENT USING THE ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide a triphenylamine derivative high in sensitivity as a positive hole transport agent for electrophotographic photoreceptors and also suitable to liquid development, to provide an electrophotographic photoreceptor high in sensitivity and also suitable to liquid development, and to provide image formation equipment using the electrophotographic photoreceptor.;SOLUTION: The triphenylamine derivative is represented by formula (1) [wherein, R¹ and R² are each H, an aryl optionally having one or more substituents, alkyl or alkoxy; Ar¹ is a (substituted) benzene ring, condensed benzene ring, heterocyclic ring or condensed heterocyclic ring; A is an alkylene group or oxygen atom; and n is 0 or 1].;COPYRIGHT: (C)2008,JPO&INPIT
