Abstract
A superimposed transfer target film and ink ribbon is moved while being sandwiched by a thermal head and a platen roller, and during execution of a thermal transfer of thermally transferring ink of the ink ribbon to a transfer layer of the transfer target film by heat of the thermal head, the transfer target film is pulled and moved while leaving a sticking portion in which the ink ribbon sticks to the transfer target film by the heat. After the thermal transfer is ended, the transfer target film stops being moved, is enabled to be loosened, and a downstream portion of the ink ribbon is wound up and stretched while leaving the sticking portion sticking to the transfer target film. While leaving the downstream portion of the ink ribbon stretched, a downstream portion of the transfer target film is wound up, and the sticking portion is peeled.
