Abstract
Density unevenness caused in an image formed with an overlap portion of nozzles is suppressed. For this purpose, a method of determining an ink ejection method includes: transporting a medium in a transporting direction; forming an image with a nozzle unit having a plurality of nozzle rows in which a plurality of nozzles for ejecting ink are arranged at a predetermined interval in an intersecting direction intersecting the transporting direction, wherein the plurality of nozzle rows are arranged parallel to each other, one end side in the intersecting direction in a particular nozzle row and the other end side in the intersecting direction in another nozzle row are overlapped with each other in the transporting direction so as to form an overlap area, and in the overlap area, the nozzle in the particular nozzle row and the nozzle in the other nozzle row are at different positions in the intersecting direction; and determining an ink ejection method from the nozzles in the overlap area, based on a density of the image.
