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 head 101S and the print paper 103 carried by the belt 111 is set larger than the head-to-paper distances of other heads 101Bk, 101C, 101M, 101Y. As a result, the mist generated by the ejection of the processing liquid from the head 101S diffuses in a recessed space formed by the heads 101Bk and 101C on both sides of the head 101S and thus hardly reaches the ink nozzle surfaces of these heads on both sides.
