PROBLEM TO BE SOLVED: To solve a problem that, in an electromagnetic induction heating system which includes a magnetic core material inserted into a heating member that is a cylindrical rotation body, and an exciting coil formed by winding wire around the magnetic core material in the direction crossing the rotation axis of the heating member, a prescribed temperature distribution in the longitudinal direction cannot be obtained, and longitudinally uniform fixability cannot be obtained in some cases when the thickness of a base layer and the electric resistance of the heating member vary.SOLUTION: In an electromagnetic induction heating system, a longitudinal temperature distribution of a heating member is detected and the drive frequency is adjusted by drive frequency setting means to adjust the longitudinal temperature distribution of the heating member to become a prescribed temperature distribution.SELECTED DRAWING: Figure 4 |
