ABSTRACT:
An ink jet recording apparatus having an ink jet recording head and a cap. The apparatus includes a recording head, the recording head having a discharge port face with a discharge port arranged thereon, and a recovery device, the recovery device including the cap for covering the discharge port face, the cap having an interior and including a body portion and an edge portion opposing the discharge port face and having a leading end, the edge portion including an elastic member for covering a periphery of the discharge port, wherein during a capping operation a plane defined by the leading end of the edge portion is not parallel to the discharge port face and the edge portion is not displaced in a direction different from a capping direction between the cap and the ink jet recording head. A part of the leading end of the edge portion in contact with the discharge port face defines a contact portion between the leading end of the edge portion and the discharge port face, and the contact portion increases during the capping operation as the leading end approaches the discharge port face and gradually comes into contact with the discharge port face, the discharge port face being capped with the entire leading end of the edge portion in contact therewith when the capping operation is terminated.
