PURPOSE:To make the transmission of heat from a heating part to a printing paper satisfactory, by a method wherein in order to remove the dent part generated in the protection film part facing the heating part, the projected part of the protection film projected on both sides of said dent part is eliminated by polishing. CONSTITUTION:A dent part 7 occurs at the part facing a heating material 3A of a protection film 6. Therefore, after providing the protection film 6, the projection part 8 of the protection film 6 existing on both sides of the dent part 7 is removed by polishing to be flattened. Therefore, no space has come to exist between a printing paper and the surface of the protection film in printing time. Then, the efficiency of the transmission of heat from the heating part 3A to the printing paper is improved. Thus, the dent part on the surface of the protection film facing the heating part can be simply eliminated and the transmission of heat from the heating part to the printing paper can be raised. |
