Title: Fixing device and image forming apparatus
Inventor: UEDA HIROSHI
IPC: G03G15/20
Filed: 2004-02-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide a fixing device that prevents foreign matter such as water vapor from sticking to a temperature sensor and to provide a image forming apparatus that has the fixing device.  <P>SOLUTION: Since a temperature sensor 76 is disposed in a space sealed by a housing 72 and a lid part 78, the temperature sensor 76 is not exposed to air containing water vapor. This prevents the temperature sensor 76 from being wet with drops of water. This also prevents foreign matter, such as paper powder and toner, floating round the fixing device 16 from sticking to the temperature sensor 76. Thus, the surface temperature of a heat roll 56 can correctly be detected. Even in the event that condensation occurs on the surface of a filter 82 and the surface gets wet with the drops of water, the drops of water are removed by a cleaning member 84, and the surface temperature of the heat roll 56 can, therefore, be detected always correctly. This enables the temperature sensor 76 to accurately control the temperature of the heat roll 56. Accordingly, toner on recording paper can be fixed with an appropriate temperature.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
