Abstract:
A pressure thermistor has a retention part, a film retained on the lower surface of the retention part in such a way that both surfaces of the film are exposed, and a thermosensitive device attached to the film. One surface of the film is rough and faces a pressure roller. The one surface of the film is increased in surface area due to rough surface. Thus, reflection of heat from the pressure roller is suppressed on the one surface of the film. Also, it becomes possible to improve the absorptivity of heat on the one surface of the film.
