Abstract:
A droplet discharge head includes a plurality of pressure chambers which communicate with a plurality of nozzles which discharge droplets, respectively; at least one common supply passage which supplies liquid to the pressure chambers; at least one common return passage which communicates with the pressure chambers and to which a part of the liquid in the pressure chambers is returned; and a plurality of energy-generating elements which generate pressure in the pressure chambers, wherein the droplet discharge head circulates liquid supplied from the common supply passage to the pressure chambers to the common return passage and discharges droplets from the nozzles when pressure is generated in the pressure chambers by the energy-generating elements, and the common supply passage and the common return passage are arranged on the same side with respect to the pressure chambers.
