PROBLEM TO BE SOLVED: To obtain a fixing device which has a fixing belt 23 having an elastic layer, a heat generation element 22 heating the fixing belt while coming into contact therewith, and a pressure member 40 opposed to the heat generation element through the fixing belt, and holding and feeding to heat recording material P transporting an image T in a nip formed by the press-contact of the fixing belt with the pressure member, and where the deformation of the elastic layer of the fixing belt and the gloss stripe of an image associated with the deformation thereof is prevented from occurring and the delay of temperature rise (warm-up time) is reduced. SOLUTION: The fixing device has means 61 to 65 for switching a pressurizing condition between the heat generation element 22 and the pressure member 40, and the pressurizing condition is switched in accordance with the states of the fixing device and the image forming apparatus.
