Abstract:
1. A fixing device, comprising: a heating roller which applies heat onto a non-fixed toner image formed on a recording medium so as to fuse said non-fixed toner image, wherein said heating roller is rotatably supported on a shaft so that a circumferential surface of said heating roller contacts said recording medium, which bears said non-fixed toner image, while rotating; and a temperature detecting unit that includes a temperature detecting element in order to detect a surface temperature of said circumferential surface of said heating roller, and a flat spring support member on which said temperature detecting element is mounted at a temperature detecting position; wherein said temperature detecting unit is disposed in such a manner that said flat spring support member press-contacts said circumferential surface of said heating roller at a contacting position residing on said flat spring support member in a rotating direction of said heating roller; and wherein said temperature detecting position of the temperature detecting unit is located upstream from said contacting position of said flat spring support member in said rotating direction of said heating roller.
