<P>PROBLEM TO BE SOLVED: To prevent image defects caused by temperature rise in a non-paper feeding area when thin paper is fed in a heating device employing an electromagnetic induction heating system using a magnetic shunt alloy having a predetermined Curie temperature. <P>SOLUTION: A heating device employing an electromagnetic induction heating system heats a material to be heated P by heat generated by an eddy current that occurs in a conductive member 1 (1a) by acting a magnetic field in the conductive member by magnetic field generating means 3. The conductive member is a magnetic shunt alloy, and the composition of which has been adjusted to have a predetermined Curie temperature. The conductive member includes cooling means 27a and 27b for cooling edges of the conductive member, and the cooling effect is improved by the cooling means when thin paper is fed, which has a fixing temperature lower than normal paper. <P>COPYRIGHT: (C)2013,JPO&INPIT |
