When a roughened pattern is formed on an image protection layer, a thermal transfer sheet is protected from being damaged or broken. A thermal head 18 is driven and controlled such that an image protection layer 15e of a thermal transfer sheet 15 is thermally transferred to a printing medium 14, and that a roughened pattern 40 is formed on the image protection layer 15e. The roughened pattern 40 is made based on a corrected pattern 40B that is obtained by correcting a basic pattern 40A that is a pattern including an island portion formed of a mass of a plurality of high-energy pixels 40a, such that the high-energy pixel 40a surrounded by the high-energy pixels 40a forming an edge area of the island portion is converted to a low-energy pixel 40b.
