PURPOSE:To prevent the occurrence of disorder of a printing position and to improve a quality of a recording picture, by preventing spreading of an electric potential distribution at an ink upheaval part, and by flying ink to a recording substance only from the ink upheaval part. CONSTITUTION:An ink holder 7 has a slit 3, a substrate 1 pierces the space of the slit 3 as it divides the slit into an upper and a lower chamber, and the blade part is caused to emerge from the opening of the slit. A plural number of electrodes 2, being electrically insulated from each other, is aligned extending from the blade part to the terminal at the other side, and each terminal is connected to a print control system 8 through a conductor 9. The opposite sides are enclosed with side plates 4, ink is held in the slit 3, and ink passes through a pipe 5 connected to the side plate 4 to be continuously fed by dint of a static water pressure based on a liquid head pressure h of both ink in an ink tank 10 and an ink upheaval part 6 in the slit 3. A signal voltage is applied between the electrode 2 and a back electrode to cause ink to fly toward a recording substance 12. |
