摘要： An ink-jet recording apparatus of one aspect of the invention comprises nozzles are arranged on an ink ejection surface in a matrix in a first direction in which a recording medium is conveyed and a second direction orthogonal to the first direction. The plurality of nozzles are grouped into a plurality of nozzle sets, each of the plurality of nozzle sets includes nozzles arranged along the second direction. The plurality of nozzle sets are spaced from one another in the first direction by first distances, each of the first distances is an integral multiple of a distance that is obtained by multiplying a unit distance by 2n-1. The unit distance corresponds to a highest resolution among first resolutions with respect to the first direction of an image to be formed on the recording medium.
