In an ink jet printing apparatus prints an image by employing a print head capable of ejecting ink from ejection ports, a suction unit draws ink from the ejection ports into an interior of the cap by applying a suction force to the interior of a cap that is covering the ejection ports. An atmosphere communication unit exposes to the atmosphere the interior of the cap that is covering the ejection ports, and a pressure increase unit increases a pressure in an internal of the print head. A control unit permits the suction unit to apply the suction force to the interior of the cap, and permits the pressure increase unit to increase the pressure in the internal of the print head before the atmosphere communication unit exposes the interior of the cap to the atmosphere in a state where the ejection ports is covered with the cap.
