Abstract
The present invention intends to eliminate the need for a temperature detecting element adapted to measure the temperature of a roll main body in an induction-heated roller apparatus, and includes an impedance calculation part that calculates the impedance of a winding, a relational data storage part that stores relational data indicating the relationship between the impedance of the winding and the temperature of the roll main body, and a roll temperature calculation part that calculates the temperature of the roll main body from the impedance obtained by the impedance calculation part and the relational data stored in the relational data storage part.
