PROBLEM TO BE SOLVED: To provide a restriction tool for the elastic layer thickness of a roller capable of manufacturing a roller obtaining good image quality by minimizing uneven thickness of the elastic layer when forming the elastic layer using a blade coating method. SOLUTION: This restriction tool A for the elastic layer thickness of the roller 2 for forming the elastic layer 3 on the roller 2 used for a copier of an electrophotographic system, facsimile and a laser beam printer, is provided with the roller 2 forming the elastic layer 3 on the surface, and a coating blade 1 facing the roller 2 with a gap between them, and a reference surface 5 is provided to the roller 2l for keeping the gap between the roller 2 and the blade 1.
