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.
