Ink-jet printer head and ink spraying method for ink-jet printer

Abstract

An ink-jet printer head is constructed with first electrodes formed on a silicon substrate on which oxidization is performed, and each having a region contacting ink to generate ink bubbles, and a region coated with insulating layers; second electrodes formed on a layer different from the first electrodes' layer, electrically isolated from the first electrodes by the insulating layers, and contacting the ink, and producing ink bubbles in the ink on receipt of electric energy; bubble chamber barriers for electrically isolating the first electrodes from the second electrodes and for constituting bubble chambers in the ink; a nozzle plate having a plurality of orifices through which the ink is sprayed on a print media; ink chamber barriers formed between the second electrodes and the nozzle plate, and leading the ink into the orifices by a steam pressure generated from the bubble chamber barriers; and ink chambers formed by the ink chamber barriers and the bubble chamber barriers, and each temporarily storing the ink introduced through ink channels.
