<P>PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus that can reduce discharging noise while suppressing variation in ink ejection amount. <P>SOLUTION: A recording head 1 includes: a plurality of ejection port 12; and a plurality of heaters 14 for heating an ink by assuming a first pulse width as a heating time, and generating bubbles and ejecting the ink from the plurality of ejection ports 12 when a first heat pulse signal having the first pulse width is input. A control section 30 continuously outputs a second heat pulse signal to the respective plurality of heaters 14 multiple times so that the second pulse width is updated at least one or more time(s) within a range where the ink is not ejected from the plurality of ejection ports 12 right before the first heat pulse signal is generated, or periodically except for the time when the first pulse signal is generated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
