ABSTRACT:
The fixing device includes a fixing unit, a pressure unit that comes into pressure-contact with the fixing unit to form a nip, and control guides. The fixing unit includes a heat roller. The pressure unit includes a pressure belt, and a pressure pad. The pressure pad is attached to a holder and pressed by a spring through a stay, thereby bringing the pressure belt into pressure-contact with the heat roller. The control guides on both sides of the pressure pad control deformation of the pressure pad in an axial direction of the heat roller to make a nip shape uniform.
