Abstract:
An ink jet recording apparatus includes an ink jet recording head having actuators that are caused to deflect so as to vary a volume of a pressure chamber according to a drive signal applied between an electrode associated with a pressure chamber from which ink is ejected and ones associated with two pressure chambers sandwiching the former, and a drive signal generator that generates a drive signal for driving the pressure chambers in the five time-divisional drive method. The drive signal generator simultaneously supplies drive signals for alleviating deflection of an actuator or actuators at the outmost position among six actuators disposed close around a pressure chamber from which ink is to be ejected to electrodes associated with the five pressure chambers close around one from which ink is not to be ejected at a timing when the ink ejection therefrom is enabled. Thus, variations in velocity and volume between ink droplets ejected that are caused due to cross-talk between chambers can be reduced.
