Abstract:
An electro-coagulation printer comprising:a rotation drum having a circumferential surface on which a film of liquid ink is formed; a plurality of electrodes which are aligned to oppositely face with the circumferential surface of the rotation drum by a prescribed gap and which are being selectively electrified; an ink supply device which is arranged in an incoming side in connection with proximity arrangement of the electrodes and the circumferential surface of the rotation drum, wherein the ink supply device supplies the liquid ink onto the circumferential surface of the rotation drum in the incoming side such as to provide the film of the liquid ink having a regulated thickness which is smaller than the gap between the electrodes and the circumferential surface of the rotation drum; and an electrolyte supply device for supplying electrolyte which contains substantially no coagulating components and which fills a remaining gap formed between the electrodes and the film of the liquid ink having the regulated thickness within the gap, wherein electrification is performed between selected electrodes and the circumferential surface of the rotation drum with intervention of the electrolyte and the liquid ink to form a desired image on the circumferential surface of the rotation drum, which is transferred onto a printing material.
