ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY, IMAGE FORMING DEVICE, AND ELECTROPHOTOGRAPHIC CARTRIDGE

摘要

Disclosed is an electrophotographic photosensitive body with high sensitivity, which is hardly affected by a transfer in the electrophotographic process. Specifically disclosed is an electrophotographic photosensitive body comprising 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 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. Further, a binder resin having an ester bond is contained in the photosensitive layer.
