Abstract:
1. An inkjet recording apparatus comprising: a recording unit that records an image by making a recording head scan a recording medium a plurality of times, the recording head including a first nozzle array and a second nozzle array overlapping each other and arranged in a predetermined direction that intersects a scanning direction in which the recording head scans a recording medium such that end portions of the first and second nozzle arrays have an overlapping portion that overlaps each other in the scanning direction, each of the first and second nozzle arrays including a plurality of ejection nozzles for ejecting ink, the plurality of ejection nozzles arranged in the predetermined direction; and a determination unit that determines ejection nozzles to be used for recording an image out of ejection nozzles corresponding to the overlapping portion, when recording an image in a region of the recording medium where an image is formed in two or more scans among the plurality of times of scans by using the ejection nozzles corresponding to the overlapping portion, so that an image can be recorded in at least one scan out of the two or more scans by using ejection nozzles both in the first and second nozzle arrays corresponding to the overlapping portion and in at least one scan out of the two or more scans by using the ejection nozzles in the second nozzle array corresponding to the overlapping portion and without using the ejection nozzles in the first nozzle array corresponding to the overlapping portion.
