An ink jet printing apparatus is provided which can produce an image in good condition without contaminating the interior of the printing apparatus or the back of the print medium if the “marginless printing” using an ink that tends to coagulate is performed. To that end, a step is provided which applies to the ink absorber the coagulation inhibiting liquid that inhibits a colorant contained in the ink from coagulating. This suppresses the coagulation of the colorant on the surface of the absorber, allowing the colorant to quickly soak into the absorber. Therefore, the colorant is prevented from depositing on the absorber surface, alleviating the problems associated with the colorant deposit.
