<p><P>PROBLEM TO BE SOLVED: To provide a fixing device accurately detecting the temperature of a fixing belt with a simple structure. <P>SOLUTION: A fixing device includes a fixing member 31, a heating member 32 composed to be able to approach and depart from the fixing member 31, an endless fixing belt 33 wound around the fixing member 31 and the heating member 32 to be able to rotate, a nip forming member to form a nip while contacting the fixing belt 33 at a position opposite the fixing roller 31, an energizing means to energize the heating member 32 to separate from the fixing member 31, and temperature detectors 36, 37 to detect the temperature of the fixing belt 33 at a position opposite the heating member 32. The temperature detectors 36, 37 are disposed opposite or in contact with the fixing belt 33 at a position H, in parallel with the moving directions X, Y of the heat roller 32, on the outermost circumference A of the displacement area of a surface of the fixing belt 33 which displaces according to the approaching and departing movement of the heat roller 32. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
