Abstract
An electrophotographic photoreceptor includes a conductive substrate and a photosensitive layer on the conductive substrate. The electrophotographic photoreceptor has an outermost surface layer that contains fluorine-containing resin particles and an antioxidant. The fluorine-containing resin particles contain 0 or more and 30 or less carboxy groups per 10carbon atoms. A decrease in weight of the antioxidant when heated at 150° C. for 10 minutes in an air atmosphere is 40 mass % or less.
