ABSTRACT:
The liquid ejection head comprises: a plurality of nozzles which eject droplets of liquid; a plurality of pressure chambers which are respectively connected to the nozzles; a common flow passage which supplies the liquid to the pressure chambers; a plurality of ejection devices which respectively cause the liquid in the pressure chambers to be ejected from the nozzles; a temperature differential generating device which generates a temperature differential between the common flow passage and each of the pressure chambers; a common flow passage temperature determining device which determines temperature of the common flow passage; a pressure chamber temperature determining device which determines temperature of each of the pressure chambers; and a control device which controls the temperature differential generating device in accordance with the temperature of the common flow passage and the temperature of each of the pressure chambers, in such a manner that the temperature differential between the common flow passage and each of the pressure chambers reaches a prescribed temperature differential.
