されたものである。For example, a method disclosed in Japanese Patent Application Laid-Open No. 52-96541 uses magnetic ink as the ink of the fused heat transfer method, and uses a magnetic attraction means provided separately from the heat supply means to apply magnetic attraction force to the ink corresponding to the thermal image. It acts and transfers. That is, as shown in FIG. 3, the thermal head 31-
The ink medium 32 - transfer paper 35 - magnet 36 are installed in this order, and the thermoplastic magnetic ink 34 of the ink medium is brought into contact with the transfer paper when heat is applied from the base film 3, 3 surface by the thermal head (directly below the head). After adhering the molten ink to the transfer paper, the ink medium is peeled off from the transfer paper and the ink is transferred. Furthermore, we have added an effect that increases the probability of molten ink contacting the transfer paper using magnetic attraction, and an effect that increases the transfer rate to the paper when the ink medium is peeled off, making it highly effective even on rough paper with poor surface smoothness. It was invented to print text and images with high quality.
