An ink-jet head includes a nozzle array including plural nozzles. The nozzle array has a first nozzle group arranged in the center thereof and second nozzle groups arranged further on outer sides than the first nozzle group. Inter-nozzle pitches of the second nozzle groups are larger than inter-nozzle pitches of the first nozzle group. A direction in which nozzles of the second nozzle group eject an ink and a direction in which nozzles of the first nozzle group eject the ink are different.

Ink-jet head and head unit

An ink-jet recording apparatus has ink-jet heads provided for respective colors including a specific color, each being formed by arranging a plurality of head units in a transversal direction perpendicular to the printing direction and a printing timing regulating section which regulates the printing timings of the respective head units so as to make the printing position of the nozzle located at an end of each of the head units of the ink-jet head of the specific color and the printing position of the nozzle located at the opposite end of the adjacent head unit are paired and made agree with each other in the printing direction.
