摘要：
An induction heating type of fixing device to fix a recording material having a toner image thereon, having a heating member, an induction coil divided into a plurality of parts, a temperature detector for detecting a temperature of the heating member, a signal generator for generating a switching signal that periodically controls permission and prohibition of energization of each of the divided induction coils, and a controller for controlling supply of a driving current to each of the divided induction coils to heat the heating member. The controller controls the energization by periodically switching the driving current to each of the divided induction coils on the basis of an energization signal that determines the permission and the inhibition of the driving currents according to a signal of temperature detected by the temperature detector, and the switching signal.
