<P>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor and the like capable of substantially exerting the effect of lubricant by optimizing a coating state of a solid lubricant, having various properties such as elongating the life of the electrophotographic photoreceptor, preventing contamination of a charge roller, and preventing chattering and curling of a cleaning blade, and stably forming high-definition images even by long-term repetitive uses. <P>SOLUTION: In this electrophotographic photoreceptor including at least a photosensitive layer and a surface layer on a support body, the surface layer is a crosslinked resin layer including crosslinked resin, and the surface layer has linear grooves noncrossing with each other. In the electrophotographic photoreceptor, the linear grooves are substantially parallel to the axial direction of the electrophotographic photoreceptor, the average width of the linear grooves is not less than 10 μm but not more than 50 μm, the average depth of the linear grooves is not less than 0.1 μm but not more than 1 μm, and the number of the linear grooves is not less than 20 but not more than 80 in a circumferential-direction measurement length of 1 mm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
