Abstract
When image formation on an image area corresponding to a recording section of a recording head is completed by executing a plurality of number of times of record scans of the recording head using a plurality of complementary thin-out patterns, scan intervals are gradually increased before execution of pre-ejection (Nos. 29 to 33), and scan intervals are gradually decreased after execution of pre-ejection (Nos. 36 to 40), so that a variation in scan intervals of the plurality of times of record scans for a single image area is limited to fall within a predetermined time range.
