Abstract: An image is formed by thermally transferring dyes of a thermal transfer sheet onto a print recording medium, and then a protection layer is formed on the formed image. The transport speed of the print recording medium in the event of thermal transferring the dyes onto the print recording medium is set higher than that in the event of thermal transferring the protection layer onto the print recording medium. Thereby, the amount of thermal energy for application in the event of protection layer formation is increased to be greater than that in the event of image formation. Thereby, occurrence of concave-convex portions formed on the printed surface in association with a density difference in the event of image formation is prevented, and concurrently, the surface pattern in the event of image protection layer formation is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent unevenness on a print surface from being generated owing to a density difference when an image is formed, and to improve a surface state when an image protective layer is formed so as to improve image quality.
SOLUTION: A dye of a thermal transfer sheet 15 is thermal-transferred to a recording medium 14, and an protective layer 15f is formed on an formed image. In this step, a carrying speed at a time when the dye of the thermal transfer sheet 15 is transferred to the recording medium 14, is made higher than that when the protective layer of the thermal transfer sheet is transferred to the recording medium 14. An amount of thermal energy applied when the protective layer is formed is thereby made larger than that when the image is formed. Hence, the unevenness on the print surface is prevented from being generated owing to the density difference when the image is formed, and the surface state when the image protective layer is formed is improved.
