ABSTRACT:
An inkjet recording apparatus includes K ejection electrodes and K gate electrodes corresponding to the K ejection electrodes, respectively, which are located at a distance from the K ejection electrodes. The K gate electrodes are divided into M blocks each having N gate electrodes electrically connected in common. 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 and a second voltage pulse is applied to a selected one of the M blocks. A voltage difference is generated between a group and a block which are selected from the N groups and the M blocks depending on an input signal, wherein the voltage difference is equal to or greater than a minimum voltage difference which causes ejection of an ejection electrode.
