Abstract:
1. An inkjet recording apparatus comprising: a recording head having a head driver including a drive pulse generator which generates, as a drive waveform of drive voltages for the piezoelectric elements, one of a plurality of drive waveforms including the head driver making the nozzles discharge amounts of ink determined respectively according to gradations of pixels constituting image data as a printing target; and a controller having wherein in at least one of the head driver and the controller, a selector is provided which selects, for the nozzles respectively, which of the drive waveforms to apply, or whether or not to apply any of the drive waveforms, to the piezoelectric elements, and when one set of image data is divided in a sub scanning direction into A bands (where A is an integer of 2 or more), and the nozzles are divided in a main scanning direction into groups each comprising A nozzles, the selector
