摘要： An ink jet printing apparatus includes a print head for printing an image on a printing medium. The print head includes a first nozzle array for ejecting a first ink and a second nozzle array for ejecting a second ink. The ink jet printing apparatus also includes a wiping member for wiping a printing face of the print head provided with the first and second nozzle arrays, and a control unit for controlling the wiping member to wipe the printing face depending on an ejection number of the first ink ejected from the first nozzle array and an ejection number of the second ink ejected from the second nozzle array, wherein the control unit controls the wiping member to wipe the printing face if the ejection number of the first ink exceeds a first threshold value or the ejection number of the second ink exceeds a second threshold value.
