Abstract
A fixing device which changes the amount of heat received by a recording paper in accordance with a portion of the recording paper with respect to a paper transporting direction. The fixing device controls a heater for heating a fixing member so as to raise the temperature of the fixing member when a trailing half of the recording paper is disposed between the fixing member and a pressure member, or controls the heater so as to decrease the temperature of the fixing member when either one of a leading end and a trailing end of the recording paper is disposed between the fixing member and the pressure member. For another example, the fixing device controls, when a recording paper is fed from the feeding tray, at least either one of the rotation of the pressure roller and the transportation of the recording paper so as not to make the leading end of the recording paper contact with a portion of the exterior circumference of the pressure roller which is in contact with the fixing roller when the pressure roller is stopped.
