Abstract:
Two arrays of ejection openings which eject relatively large amounts of ink are provided for each of different color inks and are disposed at symmetrical positions in the order of colors in a direction corresponding to a record scan. In addition, a single array of ejection openings which eject relatively small amounts of ink is disposed for at least one color ink. Since the symmetrical disposition in the color order of the ejection opening arrays which eject large amounts of ink prevents color unevenness from appearing even when the bidirectional recording is performed. Since the single array is formed of the ejection openings which eject small amount of ink, and which is used for highly precise recording, it is possible to avoid image deterioration due to the shift of dot formed positions, even when the recording head is mounted in an inclined manner attributable to the variation in manufacturing.
