a plurality of ejection opening columns which can be supplied with ink from a plurality of ink storage portions and which is greater in number than the ink storage portions, wherein at least two of the ejection opening columns that do not adjoin each other in a direction of array of the ejection opening columns can be supplied ink from one of the ink storage portions;

an ink ejection member having the plurality of ejection opening columns and a plurality of ink supply ports, the ink supply ports being arrayed in one-to-one coffespondence with the ejection opening columns to supply ink to the associated ejection opening columns; and

a flow path forming member mounted on a surface of the ink ejection member opposite the surface on which the plurality of ejection opening columns is disposed, the flow path forming member being formed with ink introduction holes to introduce ink from the plurality of ink storage portions and with ink paths to communicate the ink introduction holes to the ink supply ports,

wherein the plurality of ink introduction holes in the flow path forming member and the plurality of ink supply ports in the ink ejection member are affanged to cross each other three-dimensionally,

wherein the ink paths connecting the ink introduction holes and the corresponding ink supply ports are formed so as not to overlap other ink supply ports,

wherein the plurality of ink storage portions are equal in number to a plurality of different tones of ink, and at least one of the plurality of tones is provided with at least two sets of the ejection opening columns and the ink supply ports, and

wherein the numbers of ejection opening columns and of ink supply ports are each an odd number n which is at least five and the numbers of ink storage portions and of ink introduction holes are each (n1)/2.
