PROBLEM TO BE SOLVED: To provide a fixing device capable of prolonging the life of a releasing agent coating means and eliminating a failure in writability, the property of sending facsimile, unevenness in the oil of an OHP, etc. SOLUTION: Cam surface constituting members 20 formed like grooves are provided in two places in both end parts of the back of a bracket 7 for holding a releasing agent regulating blade 6. When releasing agent coating is carried out only by a releasing agent coating roller 3, the eccentric parts 21a of eccentric cams 21 are inserted into the grooves provided in the cam surface constituting members 20 and the edge of the blade 6 becomes a released state where it does not abut on a pressure roller 2. When a blade effect is obtained in addition to the releasing agent coating roller 3, the eccentric parts 21a of the eccentric cams 21 become a state where they are not inserted into the grooves provided in the cam surface constituting members 20 and the rubber blade 6 is abutted on the surface of the pressure roller 2 by the energizing force of a tension spring 8. The actions of the blade 6 are carried out based on a program or arbitrarily carried out by the instruction from an operation panel, etc., while the machine is working.
