PROBLEM TO BE SOLVED: To achieve the miniaturization of a recording head, and also, to minimize the adverse effect of air flows produced by ink droplets as they are ejected from a small number of ejection opening arrays. SOLUTION: A small number of first ejection opening arrays eject one of three primary colors, cyan, magenta and yellow, and a large number of second and third ejection opening arrays eject the remaining two primary colors. A fourth ejection opening array ejecting ink droplets different from the three-primary color ink droplets is disposed between the first ejection opening array and second or third ejection opening array.
