Abstract: An ink ejector includes a head movement control section (22), an ink ejection area recognition section (3), an ink ejection timing control section (23), and an ink droplet number calculating section (5). With this arrangement, it is possible to cause nozzles included in a nozzle array to eject ink at different timings and gradually increase an amount of ink to be ejected. This allows a film thickness of an ink ejection area after landing of ink droplets to be uniform. As a result, it is possible to form a good-quality film. Further, since a head (7) includes a nozzle array having a plurality of nozzles (10), it is possible to shorten the amount of time required to restore a defective pixel. Thus, it is possible to provide an ink ejector and an ink ejection control method in which a good-quality film having a uniform thickness can be formed, and the amount of time required to restore a defective pixel can be shortened.
