INK JET RECORDING HEAD, INK JET CARTRIDGE WITH INK JET RECORDING HEAD, AND INK JET RECORDING APPARATUS
摘要:
An ink jet recording head includes at least three nozzle array groups; each of the nozzle array group including, a first nozzle array including a plurality of ejection outlets for ejecting ink, and a second nozzle array including a plurality of ejection outlets for ejecting the ink, the second nozzle array being disposed adjacent to the first nozzle array with an ink supply port for supplying the ink interposed therebetween, wherein an opening area of the ejection outlets of second nozzle array is smaller than an opening area of the ejection outlets of first nozzle array, wherein the nozzle array groups eject three different kinds of inks, respectively, when the ink jet recording head moves relative to a recording material, wherein the nozzle arrays of adjacent ones of the nozzle array group are arranged in the order of the first nozzle array of one of the adjacent nozzle array groups, the second nozzle array of the one of the adjacent nozzle array groups, the second nozzle array of the other one of the adjacent nozzle array groups, and the first nozzle array of the other one of the adjacent nozzle array groups; and the recording head further including a third nozzle array provided in each of the adjacent ones of the nozzle array groups, the third nozzle array including a plurality of ejection outlets for ejecting the ink, wherein an opening area of the ejection outlets of third nozzle array is smaller than an opening area of the ejection outlets of second nozzle array, wherein the third nozzle array being disposed in the same side as the second nozzle array with respect to the ink supply port, and wherein the nozzle array group which does not constitute the adjacent nozzle array groups is supplied with the ink having a highest lightness among the three kinds of inks.
