<p>The present invention ejects a treatment liquid (22H) at a scan before a scan where ink (22C-22M) is ejected and reduces variations in a time interval from a point of the ejection of the treatment liquid to a point of the ejection of the ink, thereby enabling an increase in image performance, and longevity, low costs and reduction in size of the print head. For achieving this object, the present invention includes a treatment liquid ejection data generating unit configured to generate the treatment liquid ejection data for ejecting the treatment liquid from the print head to the unit area before the formation of the image by the ink starts. The treatment liquid ejection data generating unit generates the treatment liquid ejection data in such a manner as to eject the treatment liquid at the plural times of the scans of the print head.</p> |
