PROBLEM TO BE SOLVED: To provide a seamless belt and manufacturing method thereof to shorten a drying time and improve smoothness of an inner surface. SOLUTION: In this manufacturing method of a seamless belt 1 wherein a polymer solution is fed in a mold from feeding supplying device, the mold is rotated, and an organic solvent is volatilized and removed, a feed of the same polymer solution and removal of an organic solvent are repeated a plurality of times and the rotation speed of the mold during the organic solvent is reduced to a value lower than a maximum speed during a feed of the high molecule material solution. The so produced seamless belt 1 is centrifugally molded in a plurality of polymer layers 2 formed of a substantially same material, and forms structure where the polymer layers 2 are laminated together through a skin 3. |
