<P>PROBLEM TO BE SOLVED: To provide a heating pressurizing apparatus efficiently and stably carrying out electromagnetic induction heating of a belt for heating without the occurrence of a fault due to leaking of magnetic flux from the belt for heating as the heating pressurizing apparatus carrying out electromagnetic heating of the belt for heating in a position on a side before a nip part. <P>SOLUTION: The heating pressuring apparatus is composed of an exciting coil 27 with at least a conductive layer installed facing the belt for heating 21 which is moved circumferentially and an AC power source 28 applying AC voltage to the exciting coil. In addition, a magnetic flux collecting member 40 with non-electromagnetic induction heating property provided with an electromagnetic heating means 26 carrying out electromagnetic induction heating of the belt 21 in a position on an upstream side reaching a nip part N is installed to be positioned variably in a position on a side facing the exciting coil 27 with the belt for heating 21 in between. <P>COPYRIGHT: (C)2008,JPO&INPIT |
