Filed: 1987-02-05
Abstract: PURPOSE:To enable an image to be satisfactorily recorded still on a medium to be recorded having a comparatively low surface smoothness, by a method wherein formation of the image on a transfer recording medium and transfer of the image on the medium to be recorded are successively carried out. CONSTITUTION:A transfer recording layer 1b obtains image formation elements as cores 1c, 1d. A thermal setting bonding agent is spread on a base material 1a. A transfer recording medium 1 is constituted by fixing the image formation elements onto the base material 1a by applying thermal energy of about 80 deg.C thereto. First, by heating a transfer part 4 at 80 deg.C and besides by impressing a specific pressure thereon, only the unreacting image formation elements certain ly adhere to a recording paper 8. Then, by heating a peeling part 5 at 90 deg.C, an adhesiveness of the bonding agent 1f to the image formation element is weakened. Since no pressure is impressed on the peeling part 5, the reacting image formation element does not adhere to the recording paper 8. Therefore, only the non-reacting image formation elements which form the image are certainly transferred to the recording paper 8.
