PURPOSE: To prevent drop of surface resistance due to attachment of corona products and to obtain high image quality even under high humidity by dispersing fine metal oxide particles surface-coated with a specified fluorine-containing siloxane derivative into a protective layer.

CONSTITUTION: The electrophotographic photoreceptor has on a conductive substrate with a photosensitive layer and the protective layer containing the fine metal oxide particles surface-coated with the F-containing siloxane derivative represented by the formula in which R is an alkyl, aryl, alkylated aryl, benzyl, polyoxyalkyl, or alkoxyl group substituted by ≥1 F atoms for ≥1 H atoms, thus permitting the fine metal oxide particles to be surface-coated with the F-containing siloxane derivative and to be dispersed into a binder resin, accordingly, secondary particles not to be formed, the obtained coating fluid to be stable against time lapse and good in dispersibility, and the protective layer formed by this coating fluid to have high transparency and to be superior in resistance to environments.
