摘要： An image forming apparatus has an image bearing member rotatable in a specified direction, a developing roller for supplying developing material to a latent image formed on the image bearing member, a spacing roller rotatably supported on a shaft of the developing roller and making contact with the edge of the image bearing member in the axial direction, and a seal member having a portion that contacts the image bearing member on the upstream side of the developing roller in the direction of rotating and a portion that contacts the image bearing member on the developing roller side. The spacing roller forms the desired developing gap between the surface of the developing roller and the surface of the image bearing member. The seal member sweeps the surface of the image bearing member so as to mainly prevent the adhesion to the spacing roller of the airborne toner which is in the vicinity of the surface of the image bearing member and the surface of the developing roller. Further, the toner adhering to the surface of the image bearing member is cleaned therefrom by the seal member before the toner reaches the spacing roller. Thus, the precision of the developing gap can be maintained in the desired condition over a long period of time.
摘要翻译：图像形成装置具有能够沿指定方向旋转的图像承载部件，用于将显影材料供给到形成在图像承载部件上的潜像的显影辊，可旋转地支撑在显影辊的轴上并与显影辊接触的显影辊图像承载部件沿轴向的边缘，以及密封部件，其具有在显影辊的上游侧沿着旋转方向与图像承载部件接触的部分，以及与显影辊上的图像承载部件接触的部分侧。间隔辊在显影辊的表面和图像承载部件的表面之间形成所需的显影间隙。密封构件扫掠图像承载构件的表面，以便主要防止粘附在图像承载构件的表面附近和显影辊表面附近的空气调色剂的间隔辊。此外，在调色剂到达间隔辊之前，通过密封构件清洁附着在图像承载部件表面上的调色剂。因此，可以在长时间内将显影间隙的精度保持在期望的状态。

摘要： An image processing system includes a main image processing unit and an auxiliary unit detachably attached to the main image processing unit. The auxiliary unit includes a first drive source. The main unit on the other hand includes a second drive source and a mechanism for transporting a sheet. These drive sources are so operated that when the auxiliary unit is attached to the main unit the transporting mechanism is powered by the first drive source in the auxiliary unit and when the auxiliary unit is not attached to the main unit the transporting mechanism is powered by the second drive source in the main unit.

摘要： In a charger, a plurality of rows of air openings are provided in a shield member. The rows are elongated in the longitudinal direction of stretched corona wires and each of the rows has a plurality of air openings. The air openings are arranged in such a manner that the numbers of the air openings in opposition to the same corona wire in the nearest position are the same when counted in the direction vertical to the length of the corona wire. As a result, soiled portions in the corona wires produced by air streams passing through the air openings are uniformly distributed throughout the whole length of the charger and each part of the charger has substantially the same charging power.
摘要翻译：在充电器中，在屏蔽部件中设有多排空气开口。这些排在拉伸的电晕丝的长度方向上是细长的，并且每排都具有多个空气开口。空气开口以这样的方式布置，使得当与垂直于电晕丝的长度的方向计数时，与最近位置处的相同电晕丝相对的空气开口的数量相同。结果，通过气孔的空气流产生的电晕丝中的脏污部分均匀地分布在充电器的整个长度上，充电器的每个部分具有基本上相同的充电功率。
