    • To provide a recording liquid feed path, recording liquid container, and recording liquid feed device having the same, as well surface modifying method for the recording liquid feed device to feed efficiently a recording liquid for ejection through a feed tube. If the interior of the feed tube is not rendered hydrophilic as shown in Fig. 3A, air which has passed through a wall of the feed tube forms a bubble, which bubble adheres to an inner surface of the feed tube and obstructs a flow of the recording liquid. But if the inner surface of the feed tube is rendered hydrophilic to form a hydrophilic surface as shown in Fig. 3B, the recording liquid is conducted along the hydrophilic surface at the inner surface portion of the feed tube with the bubble adhered thereto, so that the adhesion area of the bubble to the feed tube inner surface is reduced and the bubble floats from the inner surface. Consequently, when the recording liquid is fed, the bubble can be removed easily by the flow of the recording liquid and thus the flow of the recording liquid can be prevented from being obstructed by the bubble.
    • 提供一种记录液体输送通道,记录液体容器中,并且记录具有相同的液体供给装置,作为用于在记录液体输送设备通过进料管,以有效地馈送记录液喷出孔表面改性方法。 如果如图3A所示,其中已通过的进料管形式的壁中的气泡通过空气进料管的内部不呈现亲水性,其中气泡粘附到进料管的内表面和阻碍的流动 记录液。 但是,如果进料管的内表面被亲水处理,形成亲水表面,如图3B所示,记录液体沿在与粘附在其上的气泡的进料管的内表面部分的亲水性的表面传导,所以没有 气泡进料管内表面的粘接面积减小,并且气泡从内表面浮动。 因此,当记录液被供给,气泡可以容易地通过记录液体的流动去除并因此在记录液体的流动可以根据由气泡的阻碍被防止。
