Patent ID: 8669028

Claim:
An electrophotographic photoreceptor comprising: a substrate, a photosensitive layer, and a surface protective layer, in this order, the surface protective layer comprising a crosslinked product of a curable charge transporting material and fluorinated resin particles, a content of the charge transporting material being from about 90% by weight to about 98% by weight and a content of the fluorinated resin particles being from about 2% by weight to about 10% by weight, and the surface protective layer satisfying the following Formula (I): 0.5 ≦b/a≦ 0.9 Formula (1) wherein, in Formula (1), “a” represents a ratio of fluorine atoms to the sum of carbon atoms, oxygen atoms, and fluorine atoms present in a region of the surface protective layer ranging from the photosensitive layer side surface of the surface protective layer to a point corresponding to about ⅔ of the film thickness of the surface protective layer, and “b” represents a ratio of fluorine atoms to the sum of carbon atoms, oxygen atoms, and fluorine atoms present in a region of the surface protective layer ranging from the outer surface of the surface protective layer to a point corresponding to about ⅓ of the film thickness of the surface protective layer.
