ABSTRACT:
The inkjet recording apparatus comprises: an ink ejection head in which a plurality of ink ejection ports ejecting ink are arranged; a treatment liquid ejection head in which a plurality of treatment liquid ejection ports ejecting treatment liquid are arranged; a banding information acquisition device which acquires information identifying a location where banding occurs in a dot arrangement recorded onto a recording medium by the ink ejected from the ink ejection head; an ink droplet ejection control device which controls a volume of the ink ejected by the ink ejection head according to image data; and a treatment liquid droplet ejection control device which controls droplet ejection of the treatment liquid from the treatment liquid ejection head by controlling a volume of the treatment liquid ejected from the treatment liquid ejection ports corresponding to the location where the banding occurs, as identified by the banding information acquisition device, in accordance with the volume of the ink in such a manner that the treatment liquid ejection ports corresponding to the location where the banding occurs eject the treatment liquid of a smaller volume than the volume of the treatment liquid ejected from the treatment liquid ejection ports corresponding to regions other than the location where the banding occurs.
