Abstract
A method and apparatus to control the fusing temperature of an image forming apparatus. This method of controlling the fusing temperature of an image forming apparatus having a fan to exhaust the internal air to the outside includes counting the accumulated number of sheets of paper printed in response to print commands, lowering a set point of the fusing temperature and controlling the fan to increase the amount of air to be exhausted when the accumulated number of sheets of printed paper is greater than a predetermined value. According to the method, without installing an additional temperature sensor inside the image forming apparatus, the temperature therein can be presumed and controlled by controlling the fusing temperature of the fusing roller and a fan flow rate to lower the temperature of the paper, and consequently, preventing the formation of creases in the paper.
