Ink jet printing apparatus and ink jet printing method

An ink jet printing method comprising a print head including plurality of chips each having at least one nozzle array of a plurality of nozzles through which the same color ink is ejected, the chips being connected together along a direction in which the nozzles arranged, the print head further including a connecting portion nozzle that connects a nozzle array in each chip to a nozzle array in, the adjacent chip and non-connecting portion nozzles different from the connecting portion nozzles, the ink jet printing method forming an image by allowing ink droplets to be ejected from the nozzles while relatively moving the connecting head and print media in a direction crossing the nozzle head arranging direction,

• wherein a plurality of different nozzle arrays are provided in the connecting head in the crossing direction, the connecting portion nozzle in one of the nozzle arrays overlaps the non-connecting portion nozzle in the other nozzle array, and
• control means controls ejection of ink droplets through the non-connecting portion nozzles in accordance with printing conditions when the connecting portion nozzles and the non-connecting portion nozzles are used to form the same raster extending in the relative moving direction.
