An inkjet printer includes an m number of data setters ranging from a first data setter to an m-th data setter, and an m number of print controllers ranging from a first print controller to an m-th print controller, where m is a natural number greater than or equal to 2. Upon receiving data for ink dots, an n-th data setter sets an n-th dot group including some or all of the ink dots, where n is a natural number in a range of from 2 to m. An n-th print controller causes the n-th dot group to be formed over an (n1) dot group. The first to the m-th data setters set the first to the m-th dot groups so that at least some of ink dots belonging to the first to the m-th dot groups overlap each other.

An ink-jet recording apparatus configured to record an image based on image data on a sheet, the ink-jet recording apparatus includes a first roller pair, a second roller pair, a carriage, a recording head, and a controller configured to: control the first roller pair and the second roller pair to perform intermittent conveyance of the sheet; control the carriage and the recording head to record a one-pass image on the sheet; and calculate an overlap amount, in the conveyance direction, of a one-pass image to be recorded on the sheet in a predefined one pass and a one-pass image to be recorded on the sheet in a next one pass after the predefined one pass.
