    • An ink jet recording apparatus has a head substrate, a jetting member disposed on the substrate, a recording electrode disposed so as to sandwich the jetting member and for making ink jet from the jetting member, and a separating wall for covering the recording electrode, wherein the ink is supplied from the proximal end of the jetting member and recovered in an upward direction from near the tip end of the jetting member. According to such an arrangement, it becomes possible to prevent the recording electrode from being clogged with ink adhering at the tip end thereof, and thus, the locus of the ink drop jetted from the head can be prevented from being deviated due to deviation of the jetting point on the jetting member. Accordingly, it becomes possible to provide an ink jet recording apparatus which is capable of printing an image with a high definition.
    • 喷墨记录装置具有头基板,设置在基板上的喷射构件,设置成夹着喷射构件并用于从喷射构件喷墨的记录电极和用于覆盖记录电极的分隔壁,其中 油墨从喷射构件的近端供给,并从喷射构件的顶端附近向上方回收。 根据这样的结构,可以防止记录电极在其末端粘附有墨水而被堵塞,从而能够防止从头部喷射的墨滴的轨迹由于偏移而偏离 喷射构件上的喷射点。 因此,可以提供能够以高清晰度打印图像的喷墨记录装置。
