ABSTRACT:
An inkjet recording apparatus includes: a head unit including: an ultrasonic wave generation unit that generates ultrasonic waves; an ultrasonic wave focus unit that focuses the ultrasonic waves to an ultrasonic wave focus position; an ultrasonic wave transmission unit that propagates the ultrasonic waves from the ultrasonic wave focus unit; and a wall plate that covers the ultrasonic wave generation unit, the ultrasonic wave focus unit and the ultrasonic wave transmission unit; an annular film that rotates while sliding along an exterior of the head unit; a film drive mechanism that rotates the film; and an ink application unit that applies ink over the film to form an ink layer, wherein the ultrasonic wave focus position of the head unit is directing to a position of the ink layer so as to eject an ink from the ink layer.
