COATING LIQUID FOR UNDERCOATING LAYER FORMATION, METHOD FOR MANUFACTURING COATING LIQUID, PHOTORECEPTOR HAVING UNDERCOATING LAYER FORMED BY APPLYING COATING LIQUID, IMAGE FORMING APPARATUS USING PHOTORECEPTOR, AND ELECTROPHOTOGRAPHIC CARTRIDGE USING PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide a highly stable coating liquid for undercoating layer formation, an electrophotographic photoreceptor which can form a high-quality image under various service environments and, at the same time, is less likely to develop image defects such as black spots and color spots, and has high performance and a long service life, and to provide an image forming apparatus using the photoreceptor, and an electrophotographic cartridge using the photoreceptor.;SOLUTION: The coating liquid for undercoating layer formation for an electrophotographic photoreceptor containing titanium oxide particles and a binder resin is characterized in that the volume average particle diameter of titanium oxide aggregate secondary particles in the coating liquid is 0.1 m and the cumulative 90% particle diameter is 0.3 m.;COPYRIGHT: (C)2006,JPO&NCIPI
