PROBLEM TO BE SOLVED: To allow accurate temperature detection by making thermal resistance of the base members of a non-contact temperature sensor and a correcting temperature sensor substantially equivalent to suppress drift from occurring. SOLUTION: A temperature detector 8 comprises a sensor unit 5 provided with a non-contact temperature sensor 3 opposed to an object 1, which is to be heated, and a correcting sensor 4 which corrects temperature information, and detects, in non-contact manner, the surface temperature of the object 1 which is heated by a heater source 2. The sensor unit 5 comprises a base member 6a and a can case 6b which is attached to cover the base member 6a. The base member 6a is provided with the non-contact temperature 3 and the correcting sensor 4, with the non-contact temperature 3 and the correcting sensor 4 mounted on the base member 6a through a base material 3a having equivalent thermal conductivity. A fixer uses the temperature detector 8. COPYRIGHT: (C)2003,JPO
