NEW CYANO COMPOUND, ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a compound having an excellent electron transport ability and useful as an electrophotographic photoreceptor, the positively charged type electrophotographic photoreceptor for copiers and printers with high sensitivity and an electrophotographic apparatus using the same. SOLUTION: A cyano compound has a structure represented by general formula (I) (wherein, R1s and R2s are each the same or different and denote each a 1-6C alkyl group which may have a substituent, a 1-6C alkoxy group which may have a substituent, an aryl group which may have a substituent, a 1-6C alkylamino group or a halogen atom or adjacent two R1s or R2s may mutually be bound to form a ring; and m and n denote each an integer of 0-5). The electrophotographic photoreceptor and electrophotographic apparatus use the cyano compound. COPYRIGHT: (C)2005,JPO&NCIPI
