Ink jet printing apparatus

摘要

An ink jet printing apparatus prints an image by employing a print head capable of ejecting ink through an ejection opening. The ink jet printing apparatus comprises: a blade having a distal end portion which wipes an ejection opening face of the print head where the ejection opening is formed; and a blade cleaner having a face which moves relatively to the bade in a predetermined direction while being in contact with the distal end portion of the blade. The face of the blade cleaner includes a plurality of inclined faces which are located by being shifted in the predetermined direction and inclined in the predetermined direction. The plurality of inclined faces have different inclination angles in the predetermined direction.

1. An ink jet printing apparatus for printing an image by employing a print head capable of ejecting ink through an ejection opening, the ink jet printing apparatus comprising:
a blade having an end portion which wipes an ejection opening face of the print head where the ejection opening is formed; a blade cleaner having a face which moves relative to the blade in a predetermined direction while being in contact with the end portion of the blade; and a moving unit configured to relatively move the blade and the blade cleaner so that the blade and the blade cleaner are moved closer to each other or away from each other in a direction crossing the predetermined direction, wherein the face of the blade cleaner includes a plurality of inclined faces, the plurality of inclined faces being (i) located relative to each other by being shifted in the predetermined direction and (ii) inclined in the predetermined direction, wherein the plurality of inclined faces are inclined so that a distance between the inclined faces and the end portion of the blade is increased in accordance with the relative movement between the blade and the blade cleaner, and wherein the plurality of inclined faces have different inclination angles in the predetermined direction.
