<p>An ink-jet recording head can be formed in a small size to use an increased number of kinds of inks. The ink-jet recording head has an actuator unit (1) including a pressure chamber forming plate (10) provided with a plurality of pressure chambers (2), and a plurality of pressure generators (6) that produce pressure in the plurality of pressure chambers (2), respectively, to jet ink; and a passage unit (5) stacked on the actuator unit (1) and including two or more ink storage forming plates (16A, 16B and 16C), each provided with at least one ink storage chamber (4A, 4B, 4C). The pressure chambers are grouped into two or more pressure chamber groups that correspond to two or more kinds of inks, respectively. The ink storage chambers (4A, 4B, 4C) store inks to be supplied to the pressure chamber groups (2A, 2B, 2C), respectively. <IMAGE></p> |
