    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： A sheet feeding system for an image-forming machine includes a main body having a conveying passage therethrough for guiding sheet materials and a hand insertion feed table pivotally attached to the main body for movement between a feed position in which it can be used to feed sheet materials into the conveying passage and a storage position. The sheet feeding system also includes a separate feed unit which, when the table is in its storage position, can be aligned with the main body so that sheet materials can be fed therefrom into the conveying passage. The conveying passage guides sheet materials to either a receiving section, a sorter or back into the introduction opening of the conveying passage so as to form overlapping images. An auxiliary receiving member is pivotally mounted in the receiving section for movement between a first position in which it acts to guide sheet materials from the conveying passage into the receiving section and a second potion in which it acts to guide sheet materials either to the sorter or back into the introduction opening of the conveying passage. An upper cover member is also pivoted to the main body and acts as both a cover and a guide member.

    摘要： A cleaning device for use on a transfer type electrostatic copying apparatus includes a magnetic brush cleaning device for cleaning off a magnetizable toner remaining on a photosensitive material after a transfer operation. A brush roller is disposed between the magnetic brush cleaning device and a transfer zone. A brush is arranged on a peripheral surface of a cylindrical sleeve of light transmitting material and is driven for rotation in contact with the photosensitive material. A charge eraser lamp is secured within the cylindrical sleeve. The charge on the photosensitive material or photoreceptor is almost completely erased, and consequently, the cleaning efficiency is markedly improved owing to the facilitated removal of the developing material by the magnetic brush.

    摘要翻译： 用于转印型静电复印装置的清洁装置包括用于在转印操作之后清除残留在感光材料上的可磁化调色剂的磁刷清洁装置。 刷辊设置在磁刷清洁装置和转印区之间。 刷子布置在透光材料的圆柱形套筒的外周表面上，并被驱动以与感光材料接触旋转。 电荷擦除器灯固定在圆柱形套筒内。 感光材料或感光体上的电荷几乎完全被擦除，因此由于通过磁刷有利地除去显影材料，因此清洁效率显着提高。
