摘要： PROBLEM TO BE SOLVED: To provide a noncontact temperature detecting apparatus capable of acquiring correct temperatures even in the case that stains adhere to a section on which infrared rays are incident.
SOLUTION: The noncontact temperature detecting apparatus is constituted so as to correctly detect the temperature of a first measurement surface 9 detected by a first noncontact temperature sensor 3 by a noncontact temperature sensor 11. The temperature detecting apparatus corrects temperatures detected by a second noncontact temperature sensor 4 on the basis of deviations of temperatures detected by the sensors 3 and 11. The second noncontact temperature sensor 4 detects the temperature of a second measurement surface 10 to be measured.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of detection errors due to environmental temperature changes, stains in a detecting surface, etc. in a temperature detecting apparatus using a noncontact temperature sensor.
SOLUTION: This fixing device 18 is provided with both a fixing roller 20 having a heat source 22 and a pressing roller 21 to be pressed to the fixing roller 20. The noncontact temperature sensor 50 is opposed to the circumferential surface of the fixing roller as a target measurement object. The noncontact temperature sensor is fixed to a rotating plate 26 as a sensor module 25 and connected to a correction circuit 32. The rotating plate is freely rotated on a fulcrum 27 to a horizontal position and a vertical position. When the rotating plate is rotated to the vertical position, the detecting surface is horizontally directly to a measurement surface 28, a reference object of measurement. The measurement surface is provided with the approximately same measurement surface property as that of the circumferential surface of the fixing roller so as to have the same emissivity. The measurement surface is provided with a contact temperature sensor 30 such as a thermistor for detecting a reference temperature.
