SOLUTION: As a surface transferring member 12, a sheet-like one, the thermal expansion of which is smaller than that of a cylindrical base material 110, is employed. Under the state that the surface transferring member 12 is wound around a cylindrical material to be worked 11 along one third or more of the periphery of the material to be worked 11, both the end parts of the member 12 are fixed to a sheet holding jig 13, in which the movement of one end of the surface transferring member 12 causes the relative movement of its other end by the same amount as the movement of its one end. The outermost layer of the cylindrical material to be worked 11 has a fluororesin layer 115. Both the ends of the cylindrical material to be worked 11 connect with a rotary stand 14 through core metal parts 111.  Under the state just mentioned above, the cylindrical material to be worked 11 is rotated and, under the state that the surface transferring member 12 is moved followed by the rotation of the cylindrical material to be worked 11, the cylindrical material to be worked 11 is heated with a heating means 15. As a result, stable surface transferring and film formation are obtained regardless of the scatter of the outer diameter of the cylindrical base material.
