Abstract: A surface property modifying sheet cartridge includes two reels that are disposed in parallel with a predetermined interval, a surface property modifying sheet that is provided in a tensioned state between the two reels in a manner such that end parts thereof are respectively fixed to the two reels and are wound respectively around the two reels, and a case part configured to store the two reels and the surface property modifying sheet. In the surface property modifying sheet cartridge, the case part includes a penetrating part that exposes a part of the surface property modifying sheet positioned between the two reels.

Abstract: An image forming apparatus includes a conveying unit that conveys a recording medium in a predetermined direction, a thermal transfer sheet traveling unit that causes a thermal transfer sheet to travel in a predetermined direction, a modification sheet moving unit that moves a surface modification sheet, a thermal head that applies thermal energy and thermally transfers sequentially a dye layer and a protective layer of the thermal transfer sheet onto the recording medium while the dye layer or the protective layer opposes the surface of the recording medium, and a modification sheet protecting unit disposed in a movement path of the surface modification sheet, and configured to prevent adhesion of dust to the surface modification sheet or to eliminate the adhesion.
