Abstract
An upper heat roller with an external heat source and a lower heat roller with an internal heat source are arranged with a paper transport path therebetween, in such a manner as to be pressed against each other. The lower heat roller is heated sufficiently, thereby supplying a paper sheet with sufficient heat when the paper sheet is transported through a contact region between the upper and lower heat rollers to be heated.
