PROBLEM TO BE SOLVED: To eliminate the need to keep high the heat resistance of a wiring code connected to a temperature sensor.SOLUTION: The temperature sensor 49 of a fixing device includes: a metal bracket 77 opposite to the external surface of a heat roller 47; a sensor mounting member 78 made of resin, disposed on the back surface side of the bracket 77; a sensor holding member 79, made of a thermal insulating material, disposed on the back surface side of the sensor mounting member 78; and a sensor body 80 held by the sensor holding member 79 and facing the external surface of the heat roller 47 while passing through the bracket 77 and sensor mounting member 78. The bracket 77, sensor mounting member 78, and sensor holding member 79 extend over substantially the full width in the axis direction of the heat roller 47. On the back surface side of the sensor holding member 79, a recess groove 83 is formed for arranging a wiring code connected to the sensor body 80 along the axis direction of the heat roller 47. |
