A cleaning blade which comes in elastic contact with a nozzle plate to clean a recording head is subjected to ink-receptive treatment on the surface thereof which comes in contact with the nozzle plate, such as formation of grooves or the like which can retain an ink by a capillary force. In this arrangement, an ink can be retained on the blade regardless of the rebounding of the blade shortly after the termination of cleaning operation, making it possible to prevent the ink from flying toward the recording head when the blade rebounds.
