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 formed in a pressure chamber ( 9 c) from which ink is to be ejected and electrodes formed in two pressure chambers adjacent the former, and a drive signal generator that generates drive signals for driving the recording head in the time-divisional drive method. The drive signals are applied to electrodes formed in pressure chambers 9 a, 9 b, 9 d, and 9 e, from which ink is not to be ejected so that pressure vibrations derivatively generated in the adjacent pressure chambers 9 b and 9 d are evenly dispersed to the pressure chambers 9 a, 9 b, 9 d, and 9 e. Thus, dropping of velocities of ink droplets that are subsequently ejected can be prevented and thereby printing quality can be improved.
