Patent ID: 8557487

Claim:
An electrophotographic photoconductor comprising: a conductive substrate; a photosensitive layer; and a surface layer having grooves which do not intersect each other, the photosensitive layer and the surface layer being laid over the conductive substrate, wherein the electrophotographic photoconductor is in a form of a drum or endless belt, wherein the grooves each have a width of 60 μm to 100 μm and a depth of 0.2 μm to 2 μm, wherein the standard deviation of the depths of the grooves is 1/10 or less of the average value of the depths of the grooves measured at any four places, and wherein the grooves are formed in a direction which diagonally crosses a main scanning direction and a sub-scanning direction of the electrophotographic photoconductor, wherein the sub-scanning direction is the direction in which the electrophotographic photoconductor moves or rotates, and the main scanning direction is the direction perpendicular to the sub-scanning direction.
