ABSTRACT:
A recovery mechanism is provided with an elastic blade for wiping the formation surface of ink discharge ports of a recording head by allowing the leading end of its wiping surface to slide on the formation surface of ink discharge ports of the head, and an ink jet recording apparatus is provided with such recovery mechanism. For this recovery mechanism, a guide wall unit, which is extended to the vicinity of the formation surface of ink discharge ports, is arranged along the wiping surface of the blade in a state that the blade is in a wiping operation, and then, ink adhering to the leading end of the wiping surface of the blade is guided to a gap between the guide wall unit and the blade. In this way, the flying splash of ink at the time of wiping can be suppressed for the assurance of a stabilized wiping operation, thus making it possible for the recovery mechanism and the ink jet apparatus provided therewith to perform a high-quality recording.
