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

摘要

Disclosed is a high-performance electrophotographic photosensitive body which hardly produces image defects such as black spots, colored spots or interference fringes. Specifically disclosed is an electrophotographic photosensitive body which comprises, on a conductive base whose surface has a maximum height of the profile (Rz) satisfying 0.8 <= Rz <= 2 mum, 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 not more than 0.1 mum and a cumulative 90% particle diameter of not more than 0.3 mum, as measured by dynamic light scattering.
