SYNTHESIZING METHOD FOR CHARGE TRANSPORT MATERIAL- CONTAINING AZO PIGMENT, ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

<P>PROBLEM TO BE SOLVED: To provide a synthesizing method for an azo pigment, providing an electrophotographic photoreceptor having high sensitivity and small endurance potential variation. Ž<P>SOLUTION: In this method, an azo pigment is synthesized by coupling interaction of azonium salt and a coupler component in a solvent. A charge transport material non-reactive with the azonium salt is made existent in the solvent. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
