摘要： An inkjet recording apparatus includes a recording head having three rows of nozzles which are three-phase driven and arranged in a staggered arrangement. The nozzles are arranged in the main scanning direction at an interval of L/3, where L is a pixel pitch, and each nozzle row is ejection-driven in the sequence from the last nozzle row to the forward nozzle row in the moving direction of the recording head. The recording head scans at a moving speed of 2×L×f, where f is an ejection frequency per nozzle row. After the completion of one scan, the recording medium is moved a distance of predetermined multiples of the pixel pitch in the sub-scanning direction, and in the next scan, ink is ejected onto the recording medium at pixel positions other than the pixel position on which the ink has landed in preceding scans.
