Abstract

PURPOSE: To heat, dry, and fix the transfer paper from above and below efficiently, by leading air emitted from the blower to the heater where a radiation path is formed and by controlling the supply quantity of this air by an adjusting means to fix the picture face on the heat insulating panel by hot wind.
CONSTITUTION: Hot wind supply mechanism 5 which emits hot wind toward heating surface 31 is provided in the position opposite to heating surface 31 of the heat insulating panel above transfer path l between ejected paper inlet roller 21 and outlet roller 22. This mechanism 5 is constituted by heater 6, blower 8, and wind quantity adjusting means 70 which guides and supplies prescribed air to the heater. This adjusting means 70 is constituted by aperture quantity varying member 72 fitted to housing 7, paper detector 75 provided at ejected paper inlet (a), and aperture driver 74. As a result, high-temperature hot wind is sprayed to the picture face of the transfer paper, and the transfer paper is heated from above and below and can be fixed efficiently in a short time.
