Abstract
The present invention relates to an image fixing apparatus including a fan for cooling one end region of the image fixing apparatus and a fan for cooling another end region thereof. When a temperature of the one end region reaches a cooling starting temperature, a fan corresponding to the one end portion is driven at a first rotation speed, and another fan is driven at a second rotation speed lower than the first rotation speed even if the temperature of the other end region is lower than the cooling starting temperature so as to protect the fans from thermal damages.
