An ink jet recording apparatus comprises an ink jet recording head in which a volume of a pressure chamber is caused to vary by deflecting actuators according to drive signals applied between an electrode relative to a pressure chamber from which ink is ejected and actuators relative to two pressure chambers sandwiching the former, and a drive signal generator that generates drive signals for operating the recording head in the four time-divisional drive method. The drive signal generator simultaneously supplies drive signals so that magnitudes of deflections of the outmost actuators 14 f and 14 i among four actuators disposed close around the pressure chamber 9 g from which ink is not to be ejected at a timing when the ink ejection therefrom is enabled in the time divisional driving operation become substantially equal to magnitudes of deflections of the outmost actuators 14 b and 14 e among four actuators close around pressure chamber 9 c from which ink is caused to be ejected, to electrodes relative to the outmost pressure chambers 9 f and 9 h among three pressure chambers closely disposed with the center on the pressure chamber 9 g. Thus, variations in velocity and volume between ink droplets ejected that are caused due to cross-talk between pressure chambers can be reduced.
