PROBLEM TO BE SOLVED: To provide a polishing method of reducing the erroneous determination in coating defect inspection in a polishing method of an electrophotographic photoreceptor of polishing with a polishing tool a surface of an electrophotographic photoreceptor containing a curable resin obtained by curing a compound having polytetrafluoroethylene particles and a plurality of polymerizable functional groups.SOLUTION: In a polishing method of an electrophotographic photoreceptor of polishing with a polishing tool a surface of an electrophotographic photoreceptor including a photosensitive layer on a support, a surface layer of the electrophotographic photoreceptor includes a curable resin obtained by curing a compound having polytetrafluoroethylene particles and a plurality of polymerizable functional groups, the polishing tool at least includes a base material and abrasive grains fixed thereon, the abrasive grains are a mixture of a plurality of kinds of abrasive grains having a single maximal value in a grain diameter frequency distribution, at least two of the plurality of kinds of grains have different mode diameters in the grain diameter frequency distribution, and the ratio between a mode diameter A of one of the plurality of kinds of grains having a smallest mode diameter and a mode diameter B of one of the plurality of kinds of grains having a largest mode diameter (A/B) is 0.2≤A/B≤0.8.SELECTED DRAWING: Figure 1 |
