Abstract
In an ink jet printing apparatus that performs printing by using an ink and a processing liquid that renders the ink insoluble, an effect the mist of the processing liquid or substances insolubilized by it has on the ejection performance of the ink head or processing liquid head is reduced. The distance between the processing liquid headS and the print papercarried by the beltis set larger than the head-to-paper distances of other headsBk,C,M,Y. As a result, the mist generated by the ejection of the processing liquid from the headS diffuses in a recessed space formed by the headsBk andC on both sides of the headS and thus hardly reaches the ink nozzle surfaces of these heads on both sides.
