PROBLEM TO BE SOLVED: To provide a fixing device capable of performing fixation by means of direct heat generation of induction heating even though a heating member is imparted the heat capacity below a specific capacity, and maintaining an excellent fixing performance, regardless of a kind of fixed material, and the temp. condition of a pressure roller. SOLUTION: This fixing device, provided with a magnetism generating body 7, constituted of a conductive material, letting the fixed material P that the developer image is formed thereon allowed to lie while to pass through a transfer contact section S between a rotary driven fixing belt 1 and the pressure roller 10, concentratingly induction heating the transfer contact section S, and converting the developer image on the material P to the fixed image, is equipped with a RAM preliminarily storing heat quantity data of the magnetism generating body corresponding to the kind of the material P, a photocoupler 16 detecting the kind of the material to be transferred, and a CPU reading the quantity of heat corresponding to the kind of the material P detected by receiving the detection signal of the photocoupler 16 from the RAM, and controlling the magnetism generating body in accordance with this heat capacity data being read. |
