<p>The inkjet device (1) in one embodiment of the present invention has an imaging unit (20). Said imaging unit (20) has a light source (27), a camera (26), a main body (25), and a light-emission control unit (29). The light source (27) shines illuminating light (L) on individual ink droplets (D) discharged from a plurality of nozzles (N). The camera (26) captures an image of the droplets (D) illuminated by the illuminating light (L). The main body (25) supports the light source (27) and camera (26) and is designed so as to be able to move in the direction in which the nozzles (N) are lined up. The light-emission control unit (29) is designed so as to control the amount of illuminating light (L) so as to make the amount of light taken in by the camera (26) the same each time an individual droplet (D) is imaged. A controller (15) measures the volume of each droplet (D) on the basis of the output from the camera (26) and controls a piezoelectric actuation unit (V) on the basis of the results of said measurement.</p>
