PROBLEM TO BE SOLVED: To suppress temperature drop in a non-heating portion of a heating roller to keep uniform a temperature distribution in the axial direction of the heating roller in the case that a magnetic flux generation means is arranged by being divided into a plurality of pieces. SOLUTION: An induction heating fixing device includes a heating roller 20 for heating a recording paper while rotating along a paper passing direction and induction heating type magnetic flux generation means 30a, 30b, and 30c for heating the heating roller 20. Magnetic flux generation means 30a, 30b, and 30c have a plurality of induction coils 31a, 31b, and 31c arranged by being divided in an axial direction X of the heating roller 20, and the plurality of induction coils 31a, 31b, and 31c are arranged so that magnetic fluxes at adjacent ends overlap each other and pass through the heating roller 20.
