Abstract
When the vicinity of discharge ports of the recording head of an ink jet recording apparatus is wiped for cleaning, ink is prevented from splashing in order to avoid any spoilage in the interior of a recording apparatus due to ink stains resulting from ink splashing. The apparatus is provided with a wiping blade which is shifted to abut upon or retract from a discharge port surface of the recording head. The recording head is moved so that a relative speed is generated between the wiping blade and the recording head when the wiping blade abuts upon the recording head to clean the discharge port surface thereof. The wiping blade is retracted from the recording head in a direction parting from the recording head while there is a relative speed between the recording head and the wiping blade; the wiping blade is retracted from the recording head while the wiping blade is allowed to rotate.
