Abstract
An inkjet recording apparatus includes a circulation flow channel connected to nozzle flow channels and via which ink from pressure chambers is circulated; actuators which changes pressure in the pressure chambers to eject the ink from the nozzles; and a circulating flow generation device which generates a circulating ink flow from an ink supply port side to a circulation flow channel side. A control apparatus applies ink ejection signals to the actuators for the pressure chambers in which the ink is ejected, the control apparatus also applies, to the actuators for the pressure chambers in which the ink is not ejected, continuous meniscus shaking signals causing the ink in the nozzles to shake to an extent which does not lead the ink to be ejected, wherein the control apparatus thins out the meniscus shaking signals at a plurality of different cycles.
