Abstract

The present invention has a problem of suppressing liquid gathering of an interpolation dot which interpolates a discharge defective nozzle and preventing deterioration of image quality, and the problem is solved by the present invention including: an inkjet head configured to separately discharge a large droplet, a medium droplet, and a small droplet from each of a plurality of nozzles; and a control unit which forms an image in a single-pass system by discharging the medium droplets from the plurality of nozzles respectively, and forms an interpolation dot to interpolate a discharge defective nozzle by discharging a droplet from a different nozzle when the discharge defective nozzle is present, the control unit forming the interpolation dot to interpolate the discharge defective nozzle with the use of the large droplet and forming at least one adjacent dot which is in contact with the interpolation dot with the use of the small droplet.
