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.
