Abstract

PURPOSE:To improve the fixability by constituting the titled device so that the side to which tension is applied, of a chain which is extended to a sprocket passes through on a pivot. CONSTITUTION:A pressure roller 5 is supported by a roller supporting arm 10, and provided in a state that it is pressed against a heating roller 3. Also, a motor 20 extends a chain 22 between a sprocket 21 of the motor 20 and a sprocket 7 of the pressure roller 5, and drives the pressure roller 5. Moreover, the chain 22 is set so that the side to which its tension is applied passes through on a pivot 11. That is, the roller supporting arm 10 is placed so that the side to which the tension is applied in a tangent line for connecting the sprocket 7 of the pressure roller 5 and the sprocket 21 of the motor 20, passes through the pivot 11. In such a way, a fixing failure, etc. can be prevented.
