Disclosed is a fixing device wherein a pressure belt is rotated independently of a heating roller in the paper delivery direction by second driving means including a one-way clutch which allows racing thereof in the paper delivery direction. The pressure belt is rotated at a peripheral speed less than that of the heating roller by the second driving means. The fixing device can surely perform fixation without causing defective delivery or crumple regardless of papers or plastic films.
