PROBLEM TO BE SOLVED: To provide a gloss-imparting sheet which enables a user to easily recognize that the brightening sheet can be peeled from a recording material because toner on the recording material is adequately cooled and solidified, with respect to the gloss-imparting sheet which is overlapped onto a toner image surface of recording material, is heated to fuse the toner, is peeled from the recording material after the toner of the recording material is cooled and solidified and, thereby, highly brightens a toner image. SOLUTION: The gloss-imparting sheet 33 is provided with an information part 60, where color development, color vanishment or color change occurs when the temperature becomes at least glass transition temperature of the toner or lower, preferably, when temperature becomes lower than the glass transition temperature by 20°C or larger. The information part is constituted with thermochromic microcapsule pigment, where the information relating to the peeling of the brightening sheet, preferably, is displayed by using characters there.
