The fixing device includes a fuser roller, a heat roller, an endless, fuser belt, and a pressure roller. The fuser roller has a cylindrical core of metal. The pressure roller presses against the fuser roller via the fuser belt to form a fixing nip therebetween. The first thermometer detects a first temperature at the cylindrical core of the fuser roller. The controller controls conveyance of the recording medium through the fixing nip according to the first temperature.
