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 4):
The inkjet recording apparatus according to  claim 3 , further comprising:\n a setting processing portion configured to set the start timing based on a length of the non-ejection period, wherein the drive control portion inputs the second drive signal to the piezoelectric element during a period from the start timing set by the setting processing portion to the end of the non-ejection period.
