摘要：
A cleaning device for an ink jet recording head, having at least one discharge port for ejecting recording liquid, includes a cap member for facing a region of the recording head having the discharge port therein, a supply path for supplying a fluid medium to the cap member for flow along the discharge port region and a discharge path for discharging the medium from the cap member. The flow of the medium inside the cap member from the supply path to said discharge path is constricted by a protruding portion in the cap member, which protruding portion is disposed in the cap member such that the discharge port is spaced opposite the protruding portion when the discharge port region faces the cap member, and the medium flows along the discharge port region such that a negative pressure is generated for drawing recording liquid from the discharge port into the flow of the medium.
