COATING LIQUID FOR FORMING FOUNDATION LAYER, PHOTOSENSITIVE BODY HAVING FOUNDATION LAYER OBTAINED THROUGH APPLICATION OF THE COATING LIQUID, IMAGE FORMING DEVICE USING THE PHOTOSENSITIVE BODY, AND ELECTROPHOTOGRAPHIC CARTRIDGE USING THE PHOTOSENSITIV

摘要

Disclosed are a coating liquid for forming a foundation layer having high stability; a method for producing such a coating liquid; a high-performance electrophotographic photosensitive body which is capable of forming a high-quality image under various conditions of use and hardly produces image defects such as black spots or colored spots; and an image forming device and an electrophotographic cartridge each using such an electrophotographic photosensitive body. Specifically disclosed is a coating liquid for forming a foundation layer of an electrophotographic photosensitive body, which contains metal oxide particles and a binder resin. The metal oxide particles in the coating liquid for forming a foundation layer have a number average particle diameter of not more than 0.10 µm and a cumulative 10% particle diameter of not more than 0.060 µm, as measured by dynamic light scattering.
