Abstract
A head comprises multiple nozzles on an ejection surface. The number n of nozzle rows each comprising a plurality m of nozzles arranged in a direction intersecting a first direction are disposed parallel to each other, where n and m are integers 2 or greater. Between the nozzles of each nozzle row, the nozzles of other of the nozzle rows are located as viewed in the first direction and the plurality of nozzles are located at the number m×n of dot positions. An interval defined by the number of dot positions from a dot position where one nozzle is arranged to a dot position just before a dot position where a next one of the nozzles is arranged in each row is referred to as nozzle pitch. At least one of the rows comprises two or more types of the nozzle pitches varying in the number of the dot positions.
