An apparatus for driving an ink jet record head, in which a pressure generating element and an opening is provided for each of a plurality of nozzles so as to cause an ink droplet to spout from the opening. The apparatus includes a driving signal generation unit that generates a driving signal, which includes a first driving pulse for causing a first ink droplet to spout from a nozzle and a second driving pulse for causing a second ink droplet to spout from the nozzle that is greater in size than the first ink droplet. Also included is a dot creation unit configured to select both the first driving pulse and the second driving pulse in one recording period corresponding to the recording of one pixel so as to create a larger dot than dots formed by the first and second ink droplets, and an element driving unit that drives the pressure generating element in response to the selected driving pulses.
