ABSTRACT:
When pixel is formed with respective of one ejection orifice through four times of scanning employing ejection groups formed by equally dividing ejection orifice group of an ink-jet head, number of ink droplets to be ejected in each scanning cycle is determined depending upon a half tone value of the pixel, and a remainder from division of a sum of a value indicating a current scanning cycle in the primary scanning direction for the pixel in question among a plurality of scanning cycles, and a value relating to the position of the pixel in question in the primary scanning direction by number of a plurality of scanning in a primary scanning direction. By this, the ejection orifice to be used for forming each pixel arranged in scanning direction is varied sequentially.
