Abstract
An electrophotographic apparatus is disclosed which has an electrophotographic photosensitive member and a transfer device. The photosensitive member has a conductive support and a photosensitive layer, and further has a surface layer formed of a binder resin, fluorine atom- or silicon atom-containing compound particles incompatible with the binder resin, and a fluorine atom- or silicon atom-containing compound compatible with the binder resin. In the surface layer, the proportion of fluorine atoms and silicon atoms to carbon atoms, (F+Si)/C, as measured by X-ray photoelectron spectroscopy is 0.01 to 1.0. Additionally, the transfer device is a multiple-transfer device.
