Patent ID: 8174549

Claim:
An image forming system comprising: (a) feeding means for feeding a recording medium in a predetermined direction; (b) a thermal transfer sheet having (i) an ink layer to form an image through thermal transfer on a surface of the recording medium and (ii) a protective material layer to form a protective layer protecting the image through thermal transfer; (c) a thermal transfer sheet transporting means for transporting the thermal transfer sheet; (d) a surface property reforming sheet having (i) an image printing opening disposed in such a way that the thermal transfer sheet comes into direct contact with a surface of the recording medium and (ii) a surface property reforming portion to reform the surface state of the protective layer protecting the image formed on the recording medium; (e) a reforming sheet moving means for moving the surface property reforming sheet; and (f) a thermal head to thermally transfer the ink layer or the protective material layer of the thermal transfer sheet to a surface of the recording medium, wherein, a non-adhesion treatment layer is formed on at least a surface of the surface property reforming sheet on the side to come into contact with the thermal transfer sheet.
