PROBLEM TO BE SOLVED: To provide a glossiness providing device that, when providing glossiness onto both faces of a recording medium, cools a surface onto which glossiness has already been provided to improve the quality of a glossiness image during double-sided printing.SOLUTION: There is provided a glossiness providing device 300 comprising: an endless belt 24 that conveys a recording medium P while in contact with a recording agent on the recording medium P for providing glossiness to the recording agent; a heating member 21 that has the endless belt 24 wound therearound; a pressure member 34 that applies pressure to the endless belt 24 between the heating member 21 and the pressure member; a cooling roller 91 that has the pressure member 34 wound therearound; a pressure cooling part 13 that cools the cooling roller 91 by using a liquid L; and a first housing part 310 that is arranged to surround the endless belt 24, heating member 21, pressure member 34, and cooling roller 91. The pressure cooling part 13 includes a cooling device 74 that is located outside the first housing part 310 and cools the liquid L, a roller cooling part 131 that cools the cooling roller 91, and a flow channel for the liquid L that connects the roller cooling part 131 and the cooling device 74.SELECTED DRAWING: Figure 3 【課題】記録媒体の両面に光沢を付与する場合にも、既に光沢が付与された面側を冷却することで、両面印刷時の光沢画像の高品質化を図る光沢付与装置の提供。【解決手段】記録媒体Ｐ上の記録剤に当接した状態で記録媒体Ｐを搬送して記録剤に光沢を付与するための無端状ベルト２４と、無端状ベルト２４を巻き掛けられた加熱部材２１と、加熱部材２１との間で無端状ベルト２４を加圧する加圧部材３４と、加圧部材３４を巻き掛けられた冷却ローラ９１と、冷却ローラ９１を液体Ｌを用いて冷却する加圧冷却部１３と、無端状ベルト２４と加熱部材２１と加圧部材３４と冷却ローラ９１と、を取り囲むように配置された第１筐体部３１０と、を有し、加圧冷却部１３は、第１筐体部３１０の外に位置し液体Ｌを冷却する冷却装置７４と、冷却ローラ９１を冷却するローラ冷却部１３１と、ローラ冷却部１３１と冷却装置７４とを結ぶ液体Ｌの流路とを有する光沢付与装置３００。【選択図】図３
