Patent ID: 7770990

Claim:
An inkjet recording apparatus, comprising: pressure chambers connected via nozzle flow channels to nozzles which eject ink; ink supply ports via which the ink is supplied to the pressure chambers; a circulation flow channel which is connected to the nozzle flow channels and via which the ink from the pressure chambers is circulated; actuators which changes pressure in the pressure chambers to eject the ink from the nozzles; a circulating flow generation device which generates a circulating flow of the ink in such a manner that the ink flows from an ink supply port side to a circulation flow channel side, even when the ink is ejected from the nozzles to perform recording; and a control apparatus which, during the recording, applies ink ejection signals to the actuators for the pressure chambers in which the ink is ejected, and 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 applied to the actuators for the pressure chambers in which the ink is not ejected at a plurality of different cycles.
