Title:
FIXING DEVICE AND IMAGE FORMING DEVICE EQUIPPED WITH THE SAME
Document Type and Number:
Japanese Patent JPH11125989
Kind Code:
A
Abstract:

To provide a fixing device which correctly detect the temperature of the both end parts and the central part of the periphery of a fixing body with respect to its axial direction, irrespective of the sizes of supplied transfer material, during consecutive fixing to the transfer materials, and an image forming device equipped with the fixing device.

In addition to a thermister heat-sensitive detection sensor 105 for detecting the temperature of the end parts of the fixing roller 101 with respect to its axial direction, a thermister heat-sensitive detection sensor 11 is provided for detecting the temperature of the central part of the periphery of the fixing roller 101 with respect to its axial direction. They are set so that over a period of time that one or both heaters 103 and 104, which are different in light distribution in the axial direction of the fixing roller 101, heat the fixing roller 101, the thermister heat-sensitive detection sensor 105 detects the temperature of the end parts and also the thermister heat-sensitive detection sensor 11 detects the temperature of the central part.
