Abstract
PURPOSE:To perform processing for size stabilization and to shorten an image formation time by passing recording paper which has no image through a fixing device which is held at specific temperature higher than toner fixation temperature before the start of image formation. CONSTITUTION:The set temperature of a thermistor 224 is raised from normal toner fixation temperature to specific temperature at which copying form P obtains enough heating value by once to become stable in size with an indication input of both-surface image formation or multicolor image formation, a heating member 223 in a fixing roller 221 is supplied with electric power to raise the surface temperature of the fixing roller 221 to the set temperature, and a copying form P in a blank state is passed once between the fixing roller 221 and a pressure roller 222. Consequently, the size of the copying form P is stabilized and when the passage of a specific number of copying forms P in a fixing device 22 is detected, the surface temperature of the fixing roller 222 is lowered to toner fixation temperature.
