Abstract:
An electrophotographic photoreceptor is provided, which includes: a substrate; a photosensitive layer; and a surface protective layer, in this order, in which the protective layer contains a crosslinked product of a curable charge transporting material in a content of from about 90 to 98% by weight, and fluorinated resin particles in a content of from about 2 to 10% by weight, and the protective layer satisfies Formula (1): 0.5≦b/a≦1, wherein, “a” represents a ratio of fluorine atoms to the sum of carbon atoms, oxygen atoms, and fluorine atoms present in a region of the protective layer ranging from the photosensitive layer side surface thereof to a point corresponding to about ⅔ of the thickness thereof, and “b” represents the ratio in a region of the protective layer ranging from the outer surface thereof to a point corresponding to about ⅓ of the thickness thereof.
