A liquid jetting head includes a plurality of nozzle orifices, a plurality of pressure generation chambers associated with the nozzle orifices, and a plurality of piezoelectric vibrators for respectively varying the volume of the associated pressure generation chamber to jet a liquid droplet from the associated nozzle orifice. A drive signal generator generates a plurality of drive signals, respectively driving the piezoelectric vibrators, within a single jetting cycle of the liquid jetting head. An ID data storage stores ID data which identifies the respective nozzle orifices. A correction data storage stores correction data which corrects the amount of liquid jetted from the nozzle orifice. A drive signal supplier identifies a nozzle orifice in which the jetting amount is to be corrected, through use of the ID data, and selects at least one drive signal from the plural drive signals to adjust a displacement degree of a piezoelectric vibrator associated with the identified nozzle orifice, based on the correction data.
