Liquid discharging device and liquid discharging method

An apparatus for discharging liquid which is provided with a head having liquid discharge parts for discharging droplets from nozzles,

• wherein the head has a plurality of head chips staggeringly arranged thereon for each color of droplets, the plural head chips having a plurality of the liquid discharge parts collaterally arranged therein, and
• wherein the plural head chips are so arranged in the staggering manner as to overlap at parts of adjacent head chips when viewed from the feed direction of a recording medium, and the distance between nozzles of staggeringly arranged adjacent head chips which form dots of the same color is set to be even number multiple of one pitch which corresponds to a feed length for one line of the recording medium as well as the distance between nozzles of head chips which form dots of different color is set to be even number multiple of one pitch which corresponds to a feed length for one line of the recording medium.
