ABSTRACT:
An inkjet recording apparatus includes K ejection electrodes, M electrophoresis electrodes corresponding to M blocks into which the K ejection electrodes are divided, respectively, and an electrode opposite to the K ejection electrodes. A first voltage pulse is applied to a selected one of N groups each formed by electrically connecting an i.sup.th (1.ltoreq.i.ltoreq.N) ejection electrode for each block to each other. A second voltage pulse is applied to a selected one of the M electrophoresis electrodes. Ink ejection occurs at a desired ejection electrode specified by the selected group and the selected electrophoresis electrode in the case of a predetermined voltage applied to the electrode opposite to the K ejection electrodes.
