Abstract
A fixing device for fixing a toner image to a sheet and has a fixing roller to be heated by a heat source and a pressure roller to be pressed into contact with the fixing roller. A switcher switches a pressing force between the fixing roller and the pressure roller between a first pressing force and a second pressing force lower than the first pressing force. A pressing force detector detects the pressing force between the fixing roller and the pressure roller and a temperature detector detects the temperature of the fixing roller. A storage device stores control data indicating a control temperature for the fixing roller predetermined in accordance with the number of sheets passing the fixing device, and a controller controls the temperature of the fixing roller to the control temperature by controlling the heat source in accordance with a signal sent from the pressing force detector.
