    Abstract: A fixing device includes: a pressure belt movable in a revolving motion; a fixing roller; and a pressure member for pressing an inner surface of the belt toward the roller. A fixing nip is formed between the roller and the belt while an elastically deformable surface of the roller is contacted with the belt by pressure applied by the pressure member to the belt. The pressure member includes: an elastic member for applying pressures so that greater pressure is applied to center of the roller than to the ends, the center and the ends being along axis direction of the roller; and a hard member that is disposed parallel to the elastic member on downstream side thereof in a revolving direction of the belt and applies pressures to the roller so that greater pressure is applied to the ends than to the center.
