ABSTRACT:
By controlling the temperature of a heating roller with high precision when in standby, good first-copy-out performance is obtained. In a fixing apparatus comprising a heating roller1,a pressure roller2,an induction coil3athat generates magnetic flux, and a temperature detection member (such as a thermistor)5that detects the temperature of the heating roller1,in which the heating roller1is caused to generated heat by generating an eddy current in a heat generating layer of the heating roller with magnetic flux generated by the induction coil3a,the temperature of the heating roller1is controlled by disposing the temperature detection member5in a region where the maximum heat generating capacity of the heat generating portion of the heating roller1with induction heating is not less than 1/e, and thus an unusual rise in the temperature of the heating roller1is suppressed.
