Abstract:
An inkjet recording apparatus includes a piezoelectric element, an extraction processing portion, and a drive control portion. The piezoelectric element is provided in correspondence with a nozzle, and upon input of a first drive signal, causes ink to be ejected from the nozzle. The extraction processing portion, when a print process is executed, extracts a non-ejection period during which a non-ejection state continues for more than a reference time period, from an execution period of the print process based on a plurality of pieces of image data printed in the print process, wherein ink is not ejected from the nozzle in the non-ejection state. The drive control portion inputs a second drive signal for causing the piezoelectric element to stir the ink in the nozzle, to the piezoelectric element during a partial period of the non-ejection period extracted by the extraction processing portion.

Claim (Index 7):
An inkjet recording method executed in an inkjet recording apparatus that includes a nozzle from which ink is ejected, and a piezoelectric element provided in correspondence with the nozzle, and configured to, upon input of a predetermined first drive signal, cause the ink to be ejected from the nozzle, the inkjet recording method comprising:\n when a continuous print process is executed, extracting a non-ejection period during which a non-ejection state continues for more than a predetermined reference time period, from an execution period of the continuous print process based on a plurality of pieces of image data that are printed in the continuous print process, the non-ejection state being a state in which the ink is not ejected from the nozzle; and inputting a predetermined second drive signal to the piezoelectric element during a partial or a whole period of the non-ejection period extracted by the extraction processing portion, the second drive signal causing the piezoelectric element to stir the ink in the nozzle and causing the piezoelectric element not to eject the ink from the nozzle.
