Abstract
A thermal image forming apparatus includes a platen roller which supports a medium, a print head, including a heating unit which applies heat to the medium to form an image thereon, which rotates around the platen roller and moves the heating unit to a first location facing a first surface of the medium and a second location facing a second surface of the medium, and a restricting element which rotates together with the print head. The restricting element restricts the movement of the platen roller in a transport direction of the medium so that the heating unit is placed at a printing nip formed by the platen roller and the print head when the print head is located at the first and second locations.
