摘要:
An induction heating roller device that keeps leakage current within specifications and prevents the occurrence of erroneous operations caused by common mode noise. The induction heating roller device includes an induction coil, a grounded heating roller magnetically coupled to the induction coil and heated by electro-magnetic induction. A power factor improving capacitor is connected in parallel to and near the induction coil and has a grounded intermediate point. A high-frequency power source biases the induction coil. The leakage current produced by distributed capacitance between the induction coil and the heating roller is returned to the high-frequency power source via the power factor improving capacitor. Thus, the leakage current does not flow out of the induction heating roller device.

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.
