Abstract
The disclosure provides a compact fixing device with reduced cost of wiring including electrical cables. In the fixing device, first and second wire guide members that seal a part of wires electrically connected to terminals of a temperature detection element and a part of wires electrically connected to terminals of a safety element are disposed in the internal space of a fixing film.
Claims12
A fixing device comprising:
- a tubular fixing film;
- a heater in contact with an inner surface of the fixing film;
- a temperature detection element that detects the temperature of the heater;
- and
- a safety element that, when the temperature of the heater rises to an abnormal degree, operates by the heat and interrupts power supply to the heater,
- wherein an unfixed toner image formed on a recording material is fixed to the recording material by the heat of the heater through the fixing film, and
- wherein first and second wire guide members that seal a part of wires electrically connected to terminals of the temperature detection element and a part of wires electrically connected to terminals of the safety element are disposed in an internal space of the fixing film.

A fixing device comprising:
- a tubular fixing film;
- a heater arranged in an internal space of the fixing film and in contact with an inner surface of the fixing film along a longitudinal direction of the fixing film;
- a temperature detection element that detects the temperature of the heater;
- and
- a safety element that, when the temperature of the heater rises to an abnormal degree, operates by the heat and interrupts power supply to the heater,
- wherein an unfixed toner image formed on a recording material is fixed to the recording material by the heat of the heater through the fixing film, and
- wherein a first wire guide member that seals two wires electrically connected to two terminals of the temperature detection element and a wire electrically connected to one terminal of the safety element and a second wire guide member that seals a wire electrically connected to another terminal of the safety element, are disposed in the internal space of the fixing film.
