摘要： An A.C. corona discharging device for use in the process in which discharge and exposure are accomplished contemporaneously has insulating members disposed so as to surround the discharge wire or electrode and define the opening for projecting the image of an original. The potential gradient is increased, the discharge efficiency is improved and the flow of useless current which heretofore traveled through the shielding electrode is not encountered.

摘要： A developing device for imparting triboelectrically charged developer to a surface to be developed includes a developer holding member disposed with a minute gap with respect to a latent image bearing member for holding and moving developer to a development station, a developer supply for supplying developer to the surface of the developer holding member, and a developer removing blade in contact with the developer holding member for removing the developer used for the development and remaining on the developer holding member, the blade having developer passage openings adjacent the portion which contacts the developer holding member to again impart removed developer to the developer holding means at a position downstream of the development station with respect to the movement of the developer and which is before the supply of developer is terminated at the developer supply.
摘要翻译：用于将摩擦带电的显影剂赋予待显影的表面的显影装置包括相对于用于保持和移动显影剂到显影台的潜像承载部件设置有微小间隙的显影剂保持部件，用于向显影剂供应显影剂的显影剂供应显影剂保持构件的表面和与显影剂保持构件接触的显影剂除去刮板，用于除去用于显影剂的显影剂并保留在显影剂保持构件上，所述刮板具有与显影剂保持构件接触的部分相邻的显影剂通道开口在显影装置的下游位置相对于显影剂的移动并且在显影剂供应终止于显影剂供应之前再次将去除的显影剂赋予显影剂保持装置。
