Abstract
An apparatus is capable of securely cleaning foreign matter, such as ink, attached to a discharge port surface with good efficiency, even in the case of a broad discharge port surface such as in a full-line type apparatus, and capable of preventing a discharge defect of the ink or deviation in a discharge direction, so as to perform satisfactory recording. The apparatus includes: an absorbing roller, formed of a rotatable roller-shaped porous absorbing material, for wiping/removing foreign matter, such as ink, attached to a discharge port surface, and wipers, formed of plate-shaped rubber-like elastic materials, for sweeping/removing the foreign matter attached to the discharge port surface. The absorbing roller is moved ahead when both the absorbing roller and the wiper are brought into contact with the discharge port surface and moved in an arrangement direction of discharge ports along the discharge port surface.
