PURPOSE:To provide an image-forming device which prevents partial deformation of a film and damage to a heating body even when a malfunction occurs in film driving. CONSTITUTION:A fixing device equipped with the heating body 12, the film and a pressure member detects the number of rotations or the speed of the rotation of a film drive source 28 by means of an MPU 22, and controls a heating-body drive circuit 21 so that before the number of rotations or the speed of the rotation reaches a prescribed value, the temperature of the heating body 12 is lower than a prescribed set temperature, and after the number of rotations or the speed of the rotation reaches the prescribed value, the heating body has the prescribed set temperature. |
