PROBLEM TO BE SOLVED: To provide a centerless cylindrical polishing device capable of minimizing abrasion at grinding, capable of restraining a change in outside diametrical accuracy comparatively small, capable of holding reen-out accuracy of an outside diameter, capable of stably holding a grinding object at polishing time and causing no roller trace and stain by contact with a roller, refuse and particulates coming out of a workpiece. SOLUTION: In a centerless cylindrical grinding device for removing and regenerating a paint film of a cylindrical electrophotographic function separable organic photoreceptor having an undelay layer formed of a thermosetting resin, the centerless cylindrical grinding device is characterized by arranging a presser roller 8 for pressing a workpiece between a regulating wheel 5 for imparting revolving driving by revolvingly contacting a work rest 7 for supporting the workpiece of the centerless cylindrical grinding device by the roller 8 and the roller type work rest 7.
