<p>PURPOSE:To reduce cost and make printing quality favorable, by a method wherein a magnetic toner is adhered to the face side of a recording paper by a magnet provided on the back side of the paper, and only a part required for printing is irradiated with laser light to melt a portion of the toner and to adhere the melted toner to the paper, thereby printing directly on the paper. CONSTITUTION:The recording paper 1 is fed in the direction of an arrow A, simultaneously a magnet member 2 is moved at the same velocity as that of the paper 1 along the paper 1 from the position of an adhering roller 6 to a position proximate to a cleaner 8, and a portion of the toner 3 attracted by the roller 6 is adhered uniformly to the face side of the paper 1 by the attractive force exerted by the magnet member 2. The toner 3 thus attracted is fed in the feeding direction of the magnet member 2 and the paper 1, then plastic capsules are melted by the heat generated by laser light 18 with which only a printing part is irradiated, and a dye is fused onto the paper 1. The laser light 18 is swept by a polygonal mirror 15 to selectively emit light, whereby a required character, symbol, figure or the like is writen on the paper 1.</p> |
