Patent ID: 8822114

Claim:
An electrophotographic photoreceptor comprising: a substrate; a photosensitive layer that is provided on the substrate; and a surface layer that is provided on the photosensitive layer, contains fluororesin particles, is a single layer having a thickness of 3 μm or greater, and has a cross-section, taken along a thickness direction thereof, which satisfies Expressions (1), (2), and (3) below: 0 ≦A 1 ≦0.2 ×A 4 Expression (1) 0.2 ×A 4 <A 2 ≦0.6 ×A 4 Expression (2) 0.6 ×A 4 <A 3 Expression (3) wherein, A 1 represents the ratio (%) of the area of the fluororesin particles to the total area of a first region in cross-section, in which the first region is located in a distance range of greater than or equal to 0.2 μm and less than 0.5 μm from the outermost surface of the surface layer to the substrate side; A 2 represents the ratio (%) of the area of the fluororesin particles to the total area of a second region in cross-section, in which the second region is located in a distance range of greater than or equal to 0.5 μm and less than 1.5 μm from the outermost surface of the surface layer to the substrate side; A 3 represents the ratio (%) of the area of the fluororesin particles to the total area of a third region in cross-section, in which the third region is located in a distance range of 1.5 μm to (the thickness of the surface layer-0.5 μm) from the outermost surface of the surface layer to the substrate side; and A 4 represents the ratio (%) of the area of the fluororesin particles to the total area of the cross-section.
