Summary:An ink jet recording apparatus, which is provided with a blade (14) for wiping the surface of discharge openings (13) of an ink jet recording head (3), and a blade cleaner (17) for removing ink adhering to the blade (14), comprises cleaning means (15) for cleaning the blade by enabling the blade cleaner (17) and the blade (14) to reciprocate correlatively. This cleaning means (15) is provided with means for causing the blade cleaner (17) to be in elastically contact with the blade (14) intensively without rotating the blade cleaner (17) when the cleaning means (15) moves forward, and for causing the blade cleaner (17) to rotate to be in elastically contact with the blade (14) weakly when the cleaning means (15) moves backward. With the structure thus arranged, it is possible to reduce the spreading of ink from the blade (14) into the interior of the ink jet recording apparatus significantly. Therefore, the surface of discharge openings (13) of the ink jet recording head (3) can be cleaned by means of a blade (14) in good condition to make it possible to operate cleaning in the most suitable mode.
