Patent ID: 8450036

Claim:
An electrophotographic photoreceptor comprising: a substrate; a photosensitive layer provided on the substrate; and a surface layer that is a single layer provided on the photosensitive layer to be in contact with the photosensitive layer, contains fluororesin particles, and has a thickness of 4 μm or greater, in which the cross-section obtained by cutting the surface layer along the thickness direction satisfies the following formula (1) and the following formula (2): 0 ≦A 1 ≦0.5 ×A 2 Formula (1): 0.7 ×A 3 ≦A 2 ≦1.2 ×A 3 Formula (2): wherein in the formula (1) and the formula (2), A 1 represents the proportion (%) of the area of the fluororesin particles occupying a region designated as a first region, which lies in the cross-section at a distance from the interface between the photosensitive layer and the surface layer, of from 0 μm to 0.5 μm; A 2 represents the proportion (%) of the area of the fluororesin particles occupying a region designated as a second region, which lies in the cross-section at a distance from the interface between the photosensitive layer and the surface layer, of from 1 μm to 3 μm; and A 3 represents the proportion (%) of the area of the fluororesin particles occupying the entire cross-section with respect to the entire area of the cross-section.
