Abstract
An image forming apparatus includes: a heating portion including a heating source; a pressing portion that presses the heating portion while in contact with it; a temperature detector that detects the temperature of the heating portion and/or the pressing portion; and a conveyer that guides a print sheet with a toner image through a nip portion where the heating portion and the pressing portion are in contact with each other; and a controller that controls the heat source and the conveyer. The controller controls the heating source to set the heating portion to target temperature during execution of a print job, determines a nip width magnitude, on the basis of the temperature variation of the heating portion and/or the pressing portion and heat generation of the heating source by rotating them when the print job is not being executed, and changes the target temperature on the basis of the determination.
