Abstract
A method for forming an image and a protective layer on a transfer receiving material, by thermal transfer, including supplying a thermal transfer sheet between a thermal head of a thermal printer and a platen roller, wherein the thermal transfer sheet includes color material layers and a transferable protective layer arranged in a face serial manner, and wherein the thermal head includes heat generating portions arranged substantially in parallel with each other; thermally transferring the color material layers to form an image on the transfer receiving material; thermally transferring the transferable protective layer to form a protective layer on the transfer receiving material; and shifting the relative positions of the thermal head and the transfer receiving material with respect to each other, in a direction substantially in parallel with a main scanning direction, after transferring the color material layers at least once.
