Abstract
A fixing device for fixing a toner image on a recording material includes: a cylindrical film; a plate-like heater contacting an inner surface of the film; a roller for forming a nip in cooperation with the heater through the film; and a thermo-sensitive member for detecting the temperature of the heater to interrupt electric power supply to the heater when the temperature of the heater reaches an abnormal temperature. The heater has a heat generating pattern symmetric with respect to a center line thereof extending in a direction perpendicular to a recording material feeding direction. The thermo-sensitive member is provided in a side which is opposite from a surface of the heater contacting the inner surface of the film and which is downstream of the center line of the heater with respect to the recording material feeding direction.
