An electrostatic ink jet record head of the present invention includes an ink chamber storing ink consisting of a carrier liquid and charged toner particles dispersed therein. An ejection port communicates the ink chamber to the outside of the head. An ejection electrode is disposed in the ejection port and electrically insulated from the ink. An electrophoresis electrode is positioned at the opposite side to the ejection electrode with respect to the ink chamber and electrically insulated from the ink. A control electrode is provided between the electrophoresis electrode and the ejection electrode and contacts the ink. Also, an electrostatic ink jet recorder of the present invention has, in addition to the head, a counter electrode facing the ejection port with the intermediary of a recording medium, and voltage controller for applying a particular preselected voltage to each of the discharge electrode, electrophoresis electrode, and control electrode. The voltage applied to the electrophoresis electrode is higher than a threshold voltage causing the toner particles to fly by themselves, while the voltage applied to the control electrode is lower than the threshold voltage.
