PROBLEM TO BE SOLVED: To easily produce a fixing belt (seamless cylindrical film) having sufficient functions required such as surface smoothness, heat resistance and toner release properties with good mass-productivity. SOLUTION: In the process of manufacturing a fixing belt to be used for a heating and fixing device to heat and fix a toner image transferred to an objective body (copy paper or the like), the ends 11a, 11b facing each other of a thermoplastic film 11 are overlapped and welded by heating. |
