摘要： PROBLEM TO BE SOLVED: To detect the temperature of a nip part formed by a roll and a belt in a fixing device by a contact type temperature sensor in non-contact with the roll.
SOLUTION: The belt 93 is made of an elastic member, disposed so as to cover a pressure part 94 with no tension, pressed by the pressure part 94 against a heat roll 92, and driven-rotated with the rotation of the heat roll 92. A nip head 108 is a rectangular rod member of prescribed rigidity with a pad receiver 114 formed, and configured to press the belt 93 against the heat roll 92 on the downstream side of the pad 110. A thermistor 112 is buried in nearly the center of the nip head 108. The thermistor 112 detects the temperature of the heat roll 92 through the belt 93 while coming in contact with the inside surface of the belt 93 in a position nearly the center of the nip part formed by the heat roll 92 and the belt 93. The pad 110 presses the belt 93 against the heat roll 92, and deforms in accordance with the outer peripheral surface of the heat roll 92 across the belt 93.

摘要： PROBLEM TO BE SOLVED: To provide a thermal fixing device of which the dimensional accuracy of parts is easily improved and which provides stable quality.
SOLUTION: At least one of a pair of members includes an endless belt 510, and the shape of the endless belt 510 is kept by a belt-inside supporting member 512 provided inside the belt. The belt-inside supporting member 512 is formed by extruding or drawing a metallic material, so that the dimensional accuracy of the member 512 is excellent as compared with that of a structure formed by bending and welding a metal plate. Though the dimensional accuracy of the belt inside supporting member 512 is important for obtaining a stable nip, the extruded material or the drawn material of the metallic material unnecessitates finish working for obtaining the dimensional accuracy or a part to be finish-worked is reduced even if the finish working is necessitated.
