<P>PROBLEM TO BE SOLVED: To provide a fixing device capable of accurately obtaining a surface temperature in positions different in a paper width direction of a heating and fixing member and to provide an image forming apparatus using the fixing device. <P>SOLUTION: A fixing device includes a plurality of Peltier elements D arranged along a paper width direction, in such a state that a surface to be heated Da faces the surface of a fixing belt 51 as a heating and fixing member, a cooling duct 56 for cooling a surface to be cooled Db of the plurality of Peltier elements D, a voltage detection part 59 for detecting a thermal electromotive force generated in each Peltier element D, and a control part having a ROM storing information on temperature distribution in the cooling duct 56. The fixing device is configured so that the control part obtains surface temperature of the fixing belt 51 in each position where a thermoelectric transducer is arranged by the thermal electromotive force of each Peltier element D detected by the voltage detection part 59 and the information on the temperature distribution stored in the ROM. <P>COPYRIGHT: (C)2013,JPO&INPIT |
