摘要： A cleaning device for an electrostatic photographic copying machine having a sensitive drum provided with a paper-stripping groove at one side thereof includes an upper blade for stripping residual toner from the sensitive drum, a lower blade for guiding the thus stripped toner from the surface of the sensitive drum toward a toner withdrawing device, and a groove cover covering the paper-stripping groove at least from the upper blade to the lower blade so that the groove cover will be in contact with the lower blade. Residual toner which is stripped from the surface of the sensitive drum is prevented from entering the paper stripping groove by the groove cover.

摘要： An image-forming machine includes an image-bearing member having a photosensitive material on its surface, a latent electrostatic image-forming device for forming a latent electrostatic image corresponding to image information on the photosensitive material, a developing device for developing the latent electrostatic image, a transfer device for transferring the toner image from the photosensitive material to a sheet material, a conveying mechanism for conveying the sheet material through a transfer zone, and a receiving section for receiving the sheet material conveyed through the transfer zone. An assembly provides an improved cooperation of an optical device of the image-forming device, a sheet receiving section and the developing device. A further assembly maintains a process unit having the image-bearing member and an optical unit having the optical device in a predetermined positional relationship. Another assembly facilitates mounting and detachment of the image-bearing member on and from a process unit frame.

摘要： An image-forming machine having a main body and a process unit adapted to be detachably mounted on the main body. The process unit includes a first unit having a developing device and a charging corona discharger and a second unit having a rotating drum and a cleaning device. The developing device comprises a magnetic brush mechanism comprised of a hollow cylindrical sleeve and a permanent magnet disposed within the sleeve and a blade adapted to be brought into press contact with the surface of the sleeve and to decrease sufficiently the thickness of the developer layer on the sleeve surface. The cleaning device includes an elastic blade adapted to be brought into press contact with a photosensitive member disposed on the surface of the rotating drum. The toner removed from the surface of the photosensitive member by the action of the elastic blade is recovered into an interior space of the rotating drum.

摘要： An electrostatic copying process and apparatus capable of forming copies in at least two different ratios. The formation of a copied image involves exposure scanning of the image of an original document and projecting it on a photosensitive member through an optical device. The change of the ratio of copying is achieved by changing the ratio of projection of the image of the document onto the photosensitive member by the optical device, and also changing the speed of scanning.
