ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY, METHOD FOR PRODUCING CONDUCTIVE BASE, IMAGE FORMING DEVICE AND ELECTROPHOTOGRAPHIC CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a high-performance electrophotographic photosensitive body which hardly produces image defects such as black spots, colored spots or interference fringes.

SOLUTION: The electrophotographic photosensitive body comprises, on a conductive base whose surface has a maximum height of the profile (Rz) satisfying 0.8≤Rz≤2μm, a foundation layer containing metal oxide particles and a binder resin, and a photosensitive layer formed on the foundation layer. In this electrophotographic photosensitive body, the metal oxide particles of the foundation layer dispersed in a solvent obtained by mixing methanol and 1-propanol at a weight ratio of 7:3 have a volume average particle diameter of≤0.1μm and a cumulative 90% particle diameter of≤0.3μm, as measured by dynamic light scattering.
