Abstract
An image forming apparatus includes: heating and pressing rollers for fixing a toner image; a contacting and spacing portion for contacting and spacing between the rollers; an air feeder for cooling the pressing roller during a job; a guide for the sheet having been subjected to an image fixing process; an acquiring portion for acquiring the temperature of the guide: and an executing portion for executing a warming-up process of the heating roller and the pressing roller to raise the temperatures of the heating roller and the pressing roller. The executing portion controls the contacting and spacing portion and the air feeder so that the air is fed toward the guide through between the heating roller and the pressing roller at least in a part of the warming-up process, when the temperature is lower than a predetermined temperature upon activation of a main voltage source.
