PROBLEM TO BE SOLVED: To easily keep the surface roughness of a sliding part between a blade and a roller small and accurate by constituting the blade of a supporting member and an elastic blade fixed on the supporting member and making either side surface of the blade adjacent to the edge surface of the elastic blade a ground surface. SOLUTION: This blade 1 is constituted of the supporting member 2 and the elastic blade 3 fixed on the supporting member 2. Then, projecting bodies 5 projecting from the edge surface 4 of the blade 3 are formed at both ends of the surface 4 of the blade 3, and either side surface 6a or 6b of the blade 3 is made the ground surface. It is desirable to set the ground surface as a side surface sliding on a fixing roller. Both side surfaces 6a and 6b are ground according to the use state of the blade 1. In such a case, by grinding the side surfaces 6a and 6b of the blade 3, the radius of curvature on the cross section of an edge part formed between the ground surface and the surface 4 of the blade 3 is made almost zero.
