The image forming apparatus comprises: nozzles arranged in a line fashion or a two-dimensional fashion; pressure chambers arranged respectively corresponding to the nozzles; and piezoelectric elements each of which causes ink to be discharged from the nozzle by imparting pressure to interior of the pressure chamber corresponding to the nozzle during a drive signal is impressed, wherein, when one of the nozzles discharges the ink, a drive signal is supplied to the piezoelectric element of a non-discharging nozzle neighborhood of the one of the nozzles discharging the ink, the drive signal including a drive component for driving the piezoelectric element of the non-discharging nozzle in an inverse direction to direction of the piezoelectric element of the one of the nozzles discharging the ink.
