PROBLEM TO BE SOLVED: To provide a fixing device of a heat induction system, which has a means for avoiding causing a paper non-passage section to rise in temperature due to the size of a recording material being passed along a heat roller. SOLUTION: The image heating apparatus includes the fixing device of the induction heat system, and a shielding means for shielding from a magnetic flux. The shielding means is driven by a temperature difference between the middle and each end of the fixing device. COPYRIGHT: (C)2006,JPO&NCIPI
