摘要： An image forming apparatus is provided and includes a platen roller (52) and a thermal printing head (51). The thermal printing head (51) is elastically (83) biased toward the platen roller and rotates about a pivot (52a) of the platen roller for moving between first and second positions to faces first and second surfaces (M1,M2) of a medium. A transfer portion (40) has driving and driven rollers (41,42) which are rotatably engageable with each other to transfer the media. A guiding unit (200,201,202) reduces a difference of media transfer force of the transfer portion (40) when the thermal printing head is respectively located in the first and second positions.

摘要： A thermal image forming apparatus includes a platen roller which supports a medium, a print head (51), including a heating unit which applies heat to the medium (10) to form an image thereon, which rotates around the platen roller (52) 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 (54) which rotates together with the print head. The restricting element (54) 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.
