Abstract:
An ink jet recording apparatus comprising:a recording head having a plurality of recording elements arrayed for ejecting ink drops including color materials to record recording pixels; a recording element control unit for controlling the ejection of the ink drops from the recording elements; a main-scanning unit for making the recording head relatively main-scan a recording medium in a first direction while the recording head faces to the recording medium; a sub-scanning unit for making the recording head relatively sub-scan the recording medium in a second direction while the recording head faces to the recording medium; and a scanning control unit for controlling the main-scanning unit and the sub-scanning unit; wherein the first and second directions are different from each other; wherein the recording elements are actuated with the main-scanning to record bands in which a longitudinal direction thereof is a main-scanning direction; and wherein an image is recorded by repeating the main-scanning and the sub-scanning; and wherein the recording element control unit has a recording density control unit for reducing recording density only in an area near a border portion of the bands adjacent to an unrecorded area as long as the recording density is high.
