摘要： A recording head and a recording unit are provided achieving both the reliability of ejection stability and storage stability and the prevention of a new color mixing phenomenon. The recording head has ejection orifice lines each of which ejects each of the inks constituting an ink set. The plurality of inks is stored respectively in ink cartridges each having an ink storage portion being brought into a hermetically-closed state. At least three types of inks among the inks are different in specific gravity from one another, and at least two types of inks among the at least three types of inks are different in specific gravity by 0.020 or more. The ejection orifice lines are arranged so that the total sum of differences in specific gravities between the inks to be ejected from ejection orifice lines adjacent to each other among the inks to be ejected from the ejection orifice lines becomes minimal.

摘要： An object of the present invention is to provide an ink jet ink capable of suppressing bronzing phenomenon in which a reflected light of an image looks red, is excellent in color developability, and gives an image with suppressed bleeding even when formed adjacent to an image formed with a black ink. The ink jet ink comprises water, coloring materials, and a water-soluble organic solvent, in which the coloring materials comprise at least one dye selected from the group consisting of C.I. Direct Blue 199, C.I. Direct Blue 86, and C.I. Acid Blue 9, and a pigment having a copper phthalocyanine skeleton; the water-soluble organic solvent comprises a poor medium for the pigment having the copper phthalocyanine skeleton; and a content of the pigment having the copper phthalocyanine skeleton in the ink is less than 1 mass % with respect to a total mass of the ink jet ink.
