Abstract:
An inkjet recording apparatus includes an inkjet head, a tank in which liquid to be supplied to the inkjet head is retained, and a flow path for connecting the inkjet head and the tank to each other. The inkjet head includes a head main body, liquid chambers which are built in the head main body, and in which liquid is kept under negative pressure, a nozzle plate bonded to the head main body in such a manner that the plate constitutes one wall part of each of the liquid chambers, nozzles formed in the nozzle plate in such a manner that the nozzles communicate with the liquid chambers, drive elements for causing the nozzles to eject liquid droplets, and first suction holes formed in the nozzle plate in such a manner that the holes communicate with the liquid chambers.
