<P>PROBLEM TO BE SOLVED: To provide a coating liquid for undercoating layer formation, having high stability, a high-performance electrophotographic photoreceptor which can form high-quality image even under various service environments and is less likely to develop image defects, such as black points, color points, and fogging, and to provide an image forming apparatus that uses the photoreceptor, and an electrophotographic cartridge that uses the photoreceptor. <P>SOLUTION: The coating liquid for undercoating layer formation for an electrophotographic photoreceptor comprises metal oxide particles and a curable binder resin and is such that the volume average particle diameter Mv of the metal oxide particles in the coating liquid, measured by a dynamic light scattering method, is not larger than 0.1 μm. Alternatively, the coating liquid for undercoating the layer formation for an electrophotographic photoreceptor is such that the volume average particle diameter Mv is not larger than 0.1 μm, and the ratio between the volume average particle diameter Mv and the number average particle diameter Mp, i.e., Mv/Mp, satisfies Formula (1). (1): 1.10≤Mv/Mp≤1.40. <P>COPYRIGHT: (C)2008,JPO&INPIT |
