Abstract
The image forming apparatus includes a fan motor that cools an FET, and a CPU that predicts temperature of the FET, and controls the rotation speed of the fan motor based on the predicted temperature of the FET. The CPU determines the rotation speed of the fan motor at the start of image forming operation based on predicated temperature of the FET at the time when the image forming operation starts.
