A dry-type toner is temporarily put on a printing paper with electrification by an electrifying unit and a toner supplying unit. A laser diode is driven on the basis of a video signal to emit a laser beam by which the dry-type toner put on the printing paper is melted and fixed thereon. A remaining toner that was not melted on the printing paper is eliminated by a cleaning unit. A printing by the laser beam can be realized most easily without using expensive parts such as a photosensitive material or the like and without increasing its mechanism and circuit scale. A printing apparatus includes a body circuit (4) for producing a driving signal on the basis of a video signal, an electrifying unit (10) and a toner supplying unit (11) for temporarily putting a dry-type toner on a printing paper (5) with electrification, a laser diode (3) being driven by the driving signal from the body circuit (4) to emit a laser beam to melt the dry-type toner put on the printing paper (5) with electrification by the electrifying unit (10) and the toner supplying unit (11) so that the dry-type toner thus melted is fixed on the printing paper (5) and a cleaning unit (9) for eliminating a remaining toner that is not melted on the printing paper (5).
