Abstract: 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 (9c) 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 9a, 9b, 9d, and 9e, from which ink is not to be ejected so that pressure vibrations derivatively generated in the adjacent pressure chambers 9b and 9d are evenly dispersed to the pressure chambers 9a, 9b, 9d, and 9e. Thus, dropping of velocities of ink droplets that are subsequently ejected can be prevented and thereby printing quality can be improved.
