Ink jet recording apparatus

An ink jet recording apparatus comprising:

• an ink jet recording head having a plurality of nozzles from each of which ink is ejected, a plurality of pressure chambers communicating with the respective nozzles, ink supplying means for supplying ink to the respective pressure chambers, a plurality of electrodes provided relative to the respective pressure chambers for causing ink to be ejected, and actuators that form side walls isolating the pressure chambers and are caused to deflect so as to vary a volume of the pressure chamber from which ink is to be ejected according to drive signals applied between a first electrode associating with the pressure chamber from which ink is to be ejected and two electrodes adjacent to the first electrode, and
• a drive signal generator, for driving the pressure chambers so as to concurrently eject ink droplets from every N pressure chambers, that supplies a deflection-preventing signal for preventing deflection of an outmost actuator among (N+1) actuators closely disposed with the center on a chamber that causes ink to be ejected, to at least one of two electrodes sandwiching the outmost actuator, where N=2M+1 and M≧1.
