PROBLEM TO BE SOLVED: To reduce glossiness reduction of a toner image, relative to a structure comprising no cooling means for cooling after preheating of the toner image.SOLUTION: A fixation device 20 comprises: a preheating part 30; a cooling part 40; a heating part 50; an oil removal part 60; and a fixation part 70. The fixation part 70 fixes a toner image TA formed of a toner comprising a wax W, on a sheet P. The oil removal part 60 is disposed on an upstream side of the fixation part 70 in a sheet P transport direction, and removes the wax W from the toner image TA. The heating part 50 is disposed on an upstream side of the oil removal part 60 in the transport direction, and heats the toner image TA so that temperature of the toner image TA becomes first temperature T1. The preheating part 30 is disposed on an upstream side of the heating part 50 in the transport direction, and heats the toner image TA so that the temperature of the toner image TA becomes second temperature T2 being lower than the first temperature T1. The cooling part 40 is disposed between the preheating part 30 and the heating part 50 in the transport direction and cools the toner image TA.SELECTED DRAWING: Figure 1 |
