摘要： An image-forming machine includes a detachably mountable process unit. The process unit has a rotatable drum having an electrostatographic material thereon, a corona discharger, a developing device and a cleaning device. The developing device includes a development housing for holding a developer, a developer applicator for applying the developer to the electrostatographic material, and an agitating device for stirring the developer in the development housing. An agitating member of the agitating device is arranged to prevent damage of the agitating device due to forces resisting agitation motion by the agitating member. The developer applicator has a sleeve member for holding a developer on its surface, and a developer regulating blade which regulates the developer layer thickness, on the surface of the sleeve member, to provide an uniform developer thickness in the width direction. The cleaning device includes a toner removing device for removing residual toner from the electrostatographic material, a toner collecting chamber and a toner conveying passage extending from the toner recovery housing to the toner collecting chamber. The toner removing device includes a cleaning blade which, when the process unit is mounted at a predetermined position in the image-forming machine, is moved from a non-operative position away from the electrostatographic material to an operative position wherein it is brought elastically into contact with the electrostatographic material. A toner conveying device having a coil is disposed in the toner conveying passage.

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.
