An electrostatic ink-jet recording head (100) according to the invention is provided with an ink chamber (15) for storing ink containing electrified toner; an ink path (6) leading to the ink chamber; ink ejecting portions (7, 8) provided at the tip of that ink path; electrophoretic electrodes (5, 11, 11') for shifting the electrified toner of the ink having deposited in the ink path to the ink ejecting portions by electrostatic repulsive force; and a plurality of ejecting electrodes (2a - 2h), arranged near the ink ejecting portions, for forming an electric field for providing ejecting force to the electrified toner contained in the ink having deposited in the ink path. The ejecting electrodes are controlled by ejection control electrodes (3a, 3b). The ejection control electrodes form an electric field for preventing electrified toner from being ejected from the ink ejecting portions. The plurality of ejecting electrodes (2a- 2h) are formed along the ink path, and the ejecting electrodes and ejection control electrodes are stacked over a substrate with insulating layers in-between. This configuration enables the wiring area of the electrodes in the ink-jet recording head to be reduced and to compress the size of the head. <IMAGE> |
