FUSER DEVICE AND THERMISTOR

摘要

PROBLEM TO BE SOLVED: To provide a thermistor assembly where wear resistance strap is easily exchanged. SOLUTION: A wear resistance member 210 is loosely arranged around a thermistor 174 while being brought into contact with it and placed between a bead 206 and a heating fuser material 122 so as to perfectly surround the constitution element of the thermistor. The wear resistance member has a strap or tape-shape and is provided with an opening at one end part and the other end part 216 can be inserted through the opening. The inserted end part is constituted not to be drawn from the opening onece it is inserted. The strap is loosely supported at a functioning point and easily removed by cutting it and drawing it from the periphery of the thermistor. Therefore, the new strap is arranged without disposing of the thermistor assembly.
