ABSTRACT:
A present invention provides a liquid ejection head comprising a plurality of ejection openings arranged in the feeding direction of a printing medium and a plurality of ejection energy generating elements for generating energy used for ejecting liquid from the ejection openings disposed in correspondence to the ejection openings, and subjected to the scanning movement along the printing medium transverse to the feeding direction of the printing medium, wherein the ejection openings are divided into a plurality of groups arranged parallel to the scanning movement direction while alternately offset in this direction, so that the ink droplets ejected from ejection openings located at the opposite ends of the arrangement are prevented from deflecting to the center of the arrangement and from generating white streaks when the solid printing is carried out.
