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 6):
The inkjet recording apparatus according to  claim 5 , further comprising:\n a first buffer configured to output, to the extraction processing portion, each pixel included in the print data input from the generation processing portion, in order from an upstream in the print data in a sub scanning direction at a driving interval in the drive portion; and a second buffer configured to output each pixel included in the print data input from the generation processing portion, in order from the upstream in the sub scanning direction, wherein the second buffer delays output of each pixel by a predetermined delay time compared to the first buffer, wherein the extraction processing portion counts continuous inputs of non-ejection pixels from the first buffer, and determines whether or not a continuous set of non-ejection pixels is a non-ejection pixel sequence, based on a result of counting the continuous inputs of non-ejection pixels at a time when an ejection pixel is input from the first buffer, the ejection pixel corresponding to ejection of the ink, the setting processing portion sets the start timing based on a result of counting by the extraction processing portion of the continuous inputs of non-ejection pixels in a case where the extraction processing portion determines that a continuous set of non-ejection pixels is a non-ejection pixel sequence, and the drive control portion replaces each non-ejection pixel that is input from the second buffer during a period from the start timing set by the setting processing portion until an ejection pixel is input, with the specific pixel.
