Meanwhile, heat generation in the heat generating area of the transfer sheet P, where temperature rise is quite small, is stopped when this area passes the brushes 10a and 10b, and once melted toner is cooled down again. Since toner is pressurized by the roller 16 is the case of heating to be softened and melted, it is permeated into the surface layer of transfer sheet material and cooled down as it is. Consequently, the toner is fixed on the paper P.
