摘要:
A developing sleeve (10) for a magnetic brush developing unit, which is provided with a plurality of axially parallel grooves (11) formed at a predetermined pitch in the circumferential direction on the surface thereof, is disclosed. Each of the grooves and the interfacing portion between each groove and its adjacent circumferential surface curve gradually and gently in section in the circumferential direction of the developing sleeve. The pitch for the formation of the grooves may be set to be equal to or larger than the difference in travel length between the surface of the developing sleeve and that of a photosensitive drum during the time required for a point on the photosensitive drum during the time required for a point on the photosentive drum to move along the full length of a developing area.
摘要(中):
公开了一种用于磁刷显影单元的显影套筒(10),其在其表面上沿圆周方向以预定间距形成有多个沿轴向平行的凹槽(11)。 每个槽和每个槽和其相邻的周向表面之间的接合部分在显影套筒的圆周方向上逐渐地并且缓慢地弯曲。 用于形成凹槽的间距可以设定为等于或大于显影套筒的表面与感光鼓的表面之间的行进长度差在感光鼓期间所需的时间期间 所需要的光感光鼓上的点沿着整个发展中的区域移动。
