<P>PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus that can achieve high quality picture by suppressing variation of discharge performance. <P>SOLUTION: In the inkjet recording apparatus 50 that has an inkjet recording head 53 that generates pressure in each pressurized liquid chamber 1-1-1 by driving piezoelectric elements 1-4 provided in a plurality of pressurized liquid chambers 1-1-1 that communicate with the nozzle holes 2-1 respectively, and discharge the ink droplet from each nozzle hole 2-1 by the generated pressure, each piezoelectric element 1-4 has a counting means that is driven by switching at least a part of the driving wave forms repeatedly output from a reference potential and counts the driving number of times of each piezoelectric element 1-4, counts the driving number of times of each piezoelectric element 1-4 after through up of the drive waveform to the reference potential, classifies the driving state of each piezoelectric element 1-4 into the pattern that is provided beforehand according to this counting result, and changes the timing of through down of the drive waveform based on the pattern. <P>COPYRIGHT: (C)2013,JPO&INPIT |
