    • An object of the invention is to provide an image forming apparatus which can form an image having high quality. The image forming apparatus of the invention at least comprises: a supply section having a toner carrier; a counter electrode disposed facing the toner carrier; a control electrode which is interposed between these toner carrier and counter electrode and which comprises an insulating substrate, a plurality of gates which are formed on the insulating substrate, and two-layer electrode groups composed of a plurality of electrodes individually provided on the peripheries of the plurality of gates; and a control mechanism which can apply a predetermined potential to individual electrodes, the image forming apparatus being constructed in a manner that the predetermined potential is applied to the electrode in a controlled fashion so that the passage of toner through the gate is controlled, and thus an image is formed on a surface of a recording medium fed between the control electrode and counter electrode. Further, the image forming apparatus includes two half-electrode pieces formed by diving each electrode of electrode group on the counter electrode side out of the electrode groups vertically to a paper feed direction, and times of applying a potential to the half-electrode pieces in order to project the toner at a certain angle in a direction vertical to the toner carrier and the counter electrode.
    • 本发明的目的是提供一种可以形成高品质图像的图像形成装置。 本发明的图像形成装置至少包括:具有调色剂载体的供应部分; 面对调色剂载体设置的对电极; 介于这些调色剂载体和对电极之间的控制电极,其包括绝缘基板,形成在绝缘基板上的多个栅极和由分别设置在绝缘基板周围的多个电极组成的两层电极组 多个门; 以及可以对各个电极施加预定电位的控制机构,图像形成装置以预定电位以受控的方式施加到电极的方式构造,使得调色剂通过栅极的通过被控制,因此 在馈送在控制电极和对电极之间的记录介质的表面上形成图像。 此外,图像形成装置包括两个半电极片,其通过在相对电极侧的电极组的每个电极垂直于送纸方向垂直于电极组而形成,并且将电位施加到半电极片的次数 以便在垂直于调色剂载体和对电极的方向上以一定角度投影调色剂。

    • As a wound dressing that includes a perforated material having through-holes, in which the perforated material can be coated with a low-adhesive resin without closing the through-holes, and that has excellent adhesion prevention properties to wounds, provided is a wound dressing 1 that includes a sheet-shaped perforated material 11 having through-holes 111 and a low-adhesive resin 12 with which at least one face of the perforated material 11 is coated without closing the through-holes 111, the perforated material 11 is a knitted fabric or a woven fabric formed of a multifilament, and the perforated material 11 has an average opening area of the through-holes 111 of 0.02 to 1.2 mm2 and an average number of through-holes of 40 to 220 cm−2. By designing the opening area of the through-hole 111 and the number of through-holes 111 in the perforated material 11 within the particular numerical ranges, such a wound dressing can be prevented from adhering to granulation tissues that invade the through-holes 111 and can ensure sufficient permeation properties of exudate through the through-holes 111.
    • 作为包含具有通孔的穿孔材料的伤口敷料,其中多孔材料可以用低粘合剂树脂涂覆而不关闭通孔,并且对伤口具有优异的防粘连性,提供了一种伤口敷料 如图1所示,包括具有通孔111的片状穿孔材料11和低密度树脂12,多孔材料11的至少一个表面与该多孔材料11的至少一个表面相结合而不关闭通孔111,多孔材料11是针织物 织物或由复丝形成的织物,并且穿孔材料11具有0.02至1.2平方毫米的通孔111的平均开口面积和40至220厘米-2的通孔平均数。 通过在特定数值范围内设计通孔111的开口面积和穿孔材料11中的通孔111的数量,可以防止这种伤口敷料附着在侵入通孔111的造粒组织和 可以确保渗透物通过通孔111的充分渗透性。
