    • A plurality of blade tips 4, 5 are provided at the distal end of a blade cylinder having a rotation axis. The blade tips 4, 5 are arranged along a rotation direction at intervals. Each of the blade tips 4, 5 has an outside blade 6 at a farther position from the rotation axis and an inside blade 7 at a closer position to the rotation axis. Each outside blade 6 and the corresponding inside blade 7 are arranged next to each other while being displaced in the rotation direction with the stepped cutting edge 8 in between. In the blade tip 4, which is one of the blade tips 4, 5 adjacent to each other in the rotation direction, the sum of the number of the cutting edge 9 in the outside blade 6 and the number of the cutting edges 11, 12 in the inside blade 7 is three. In the other blade tip 5, the sum of the number of the cutting edge 9 in the outside blade 6 and the number of the cutting edge 10 in the inside blade 7 is two.
    • 多个叶片尖端4,5设置在具有旋转轴线的叶片滚筒的远端。 叶片尖端4,5间隔地沿旋转方向排列。 每个叶片尖端4,5具有位于距离旋转轴线更远的位置的外侧叶片6和与旋转轴线更靠近的内侧叶片7。 每个外刀片6和相应的内刀片7彼此相邻布置,同时沿着旋转方向位移,台阶式切割刃8在其间。 在作为旋转方向上彼此相邻的叶片尖端4,5之一的叶片尖端4中,外侧叶片6中的切削刃9的数量与切削刃11,12的数量之和 在内刀片7中是三个。 在另一个叶片尖端5中,外侧叶片6中的切削刃9的数量与内部刀片7中的切削刃10的数量之和为2。

    • An electrophotography developing apparatus has been developed which can protect a developer holder and a layer thickness control member from damage. The device also prevents internal scattering of the developer while preventing a surplus supply of the developer to both ends on the peripheral surface of the developer holder. The unique advantages of the invention are derived through the utilization of sealing members having different elastic properties, which assume both bulk removal of excess developer while providing the needed uniform developer thickness. Another embodiment of the invention has the width of the layer thickness control member in a longitudinal direction set wider than the width of the developer holder in a longitudinal direction, and both side edges of the layer thickness control member are positioned outside both side edges of the developer holder. Proper sealing is assured by having the inner side edges of the sealing member positioned inside the side edges of the developer holder and outside the side edges of the image area of the image holder.
    • 已经开发了可以保护显影剂保持器和层厚控制构件免于损坏的电子照相显影装置。 该装置还防止显影剂的内部散射,同时防止显影剂在显影剂载体的外周表面上的两端的多余的供应。 本发明的独特优点是通过利用具有不同弹性性质的密封构件来实现,其同时提供了大量除去过量显影剂同时提供所需均匀的显影剂厚度。 本发明的另一实施例具有纵向方向上的层厚度控制构件的宽度,其宽度大于显影剂保持器在纵向上的宽度,并且层厚度控制构件的两个侧边缘位于 开发商持有人 通过使密封构件的内侧边缘位于显影剂保持器的侧边缘的内侧并且位于图像保持器的图像区域的侧边缘的外侧来确保适当的密封。
