PURPOSE:To decrease black and white streaks and unevenness in density occurring around a place where areas of images recorded by each one of horizontal scannings adjoin each other by a method wherein a recording head is moved in the vertical scanning mode so that the second image area is partially placed on top of the first image area. CONSTITUTION:The first image area is recorded by making an ink jet recording head operated in the horizontal scanning mode. In proceeding to the recording of the second image area by making the recording head move in the vertical scanning mode after completion of the recording of the first image area, the vertical scanning is made so that ejection ports No.1-No.3 are operated in overlapping the first image area. Pixels in the area covered with the above- mentioned overlapping are applied with two times of ink jetting; namely one ink jetting per each of two scannings. The density of the pixels in the said area is controlled by total amount of ink droplets ejected thereto. Thereby black and white streaks and un-evenness in the density occurring around the place where the areas of images recorded by each of the scannings adjoin each other are considerably reduced. |
