<P>PROBLEM TO BE SOLVED: To provide a noncontact temperature detector capable of restraining stain from being deposited, without increasing the number of part items, by simple constitution. <P>SOLUTION: This noncontact temperature detector 23 has an infrared thermosensitive type noncontact thermistor 24a, a transparent casing 24b provided to cover the periphery of the thermistor 24a, an infrared absorption film 24c provided in a portion getting incident with an infrared ray into the thermistor 24a on an outer surface of the casing 24b, and a titanium oxide coating film 24d formed on a surface of the infrared absorption film 24c and having a photocatalyst function. The titanium oxide coating film 24d formed on the infrared absorption film 24c is irradiated with an ultraviolet ray emitted from an ultraviolet diode 26 to remove a toner or the like deposited on the coating film 24c by the photocatalyst function. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
