INDUCTION HEATING DEVICE, FIXING DEVICE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To separately drive a plurality of heating coils.SOLUTION: There is provided an induction heating device that heats a heating body by an induction heating system using a plurality of induction heating coils, the induction heating device including: a first coil driving part that has a voltage control circuit controlling a voltage to be supplied to the induction heating coils provided on the front stage and drives a first induction heating coil of the plurality of induction heating coils on the basis of a driving signal; a second coil driving part that is not provided with the voltage control circuit and drives a second induction heating coil of the plurality of induction heating coils on the basis of the driving signal; and a control part that controls the output of the driving signal and a drive stop signal for stopping the input of the driving signal to the second coil driving part. While the control part outputs the drive signal and outputs the drive stop signal, the drive of the second induction heating coil is stopped, and the first induction heating coil is driven.
