MEMO:
The term IH stands for "induction heating."
When high-frequency current is supplied to a coil arranged inside a heater unit, a high-frequency magnetic field develops around the coil. The filed serves
to permit the flow of eddy current (induction current) to the fixing roller, causing the roller to heat on its own.
