ABSTRACT:
In order to prevent non-sheet passing portion temperature rise occurred in a non-sheet passing area of an electromagnetic induction heating member1, leakage of magnetic flux is reduced by setting a Curie temperature of the heating member1to be smaller than an acceptable upper limit temperature and setting a thickness of the heating member so that a thickness tk in a Curie temperature arrival area (P1−P2) is larger than a thickness tn in a Curie temperature non-arrival area P2which is a conveyance area of a material to be heated having a minimum passing size.
