Abstract
An induction heating roller apparatus has a heating roller for generating heat with an induction current by being magnetically coupled to an induction coil, and a plurality of induction coils placed in a dispersed state in an axial direction inside the heating roller and also set such that adjacent heating rollers are in mutually reversed winding directions so that generated flux has the same polarity. A high frequency power supply is provided for supplying high frequency power to the plurality of induction coils.
