Abstract
An inkjet head includes: a pressure chamber; an actuator which expands and contracts volume of the pressure chamber; an ink supply flow channel; an individual supply flow channel having one end connected to the ink supply flow channel and another end connected to the pressure chamber, for guiding ink from the ink supply flow channel to the pressure chamber; a nozzle which ejects the ink; a nozzle flow channel having one end connected to the pressure chamber and another end connected to the nozzle, for guiding the ink from the pressure chamber to the nozzle; an ink recovery flow channel; an individual recovery flow channel having one end connected to the nozzle flow channel at a prescribed connection position set at an intermediate point of the nozzle flow channel and another end connected to the ink recovery flow channel, for guiding the ink from the nozzle flow channel to the ink recovery flow channel; an ink flow generation device which generates a flow of the ink from the nozzle flow channel toward the individual recovery flow channel; and a control device which controls driving of the actuator so as to drive the actuator in such a manner that, when performing ejection, volume o…
