ABSTRACT:
A recording head having an ejection portion group for ejecting a black ink, and ejection portion groups for ejecting color inks is used. When a black image to be printed by the black ink is present adjacent to a color image to be printed by the color ink, a black image portion adjacent to the color image and a black image portion which is not adjacent to the color image are formed in different scans, thereby obtaining a high-quality image from which ink blurring at a boundary portion between the black and color images is eliminated.
