Abstract
An electrophotographic photoreceptor including an electroconductive substrate; a photosensitive layer located overlying the electroconductive substrate and including a resin; and a surface layer including a filler and a binder resin, wherein the surface layer and the photosensitive layer have a continuous structure, and wherein the surface layer satisfies the following relationship: σ≦D/5, wherein D represents an average of maximum thicknesses of the surface layer in units of micrometers in 20 segments of 5 μm wide when a portion of a cross section of the photoreceptor of 100 μm wide is divided into the 20 segments, and σ represents a standard deviation of the 20 maximum thicknesses.
