    摘要： An image-forming machine including a process unit (6) to be mounted detachably. The process unit (6) has a rotating drum (16) having an electrostatographic material disposed on it peripheral surface, a corona discharger (22) for uniformly charging the electrostatographic material, a developing device (10) and a cleaning device (18). The corona discharger (22) has a grid electrode (204) formed of a piece of a conductive thin metallic plate. The developing device (10) include a development housing (50) for holding a developer (60), a developer applicator means (72) for applying the developer (60) in the development housing (50) to the electrostatographic material, and an agitating means (74; 128; 138) for stirring the developer (60) in the development housing (50). The agitating member (88; 130; 150) employs means for preventing damage of the agitating member even when an excessively large resistance is exerted by the developer (60). The developer applicator means (72) has a sleeve member (76) holding a developer (60) on its surface and a developer regulating blade (84) which can adjust the layer of the developer (60) held on the surface of the sleeve member (76) to an uniform thickness all the way in the width direction. The cleaning device (18) includes a toner removing means (30) for removing a residual toner from the electrostatographic material, a toner collecting chamber (34) and as toner conveying passage (36) extending from a toner recovery housing (32) to the toner collecting chamber (34). The toner removing means (30) is constructed of a cleaning blade which when the process unit (6) is mounted at a predetermined position in the image-forming machine, is moved from a non-operative position at which it is away from the electrostatographic material to an operative position at which it is brought elastically into contact with the electrostatographic material. A toner conveying means (44) comprised of a coil is disposed in the toner conveying passage (36).

    摘要： An image-forming machine is provided comprising a cleaning device for removing residual toner from an electrostatographic material. The cleaning device includes a toner collecting chamber 34, a toner conveying passage 36, a toner transferring means 38 for transferring toner received to one end of a toner recovery housing 32 and a toner conveying means 44 for conveying toner from the toner recovery housing to a toner collecting chamber 34 through the toner conveying passage 36. The toner transferring means comprise a rotating shaft 40 extending in the toner recovery housing 32 and adapted to be rotated in a predetermined direction. The toner conveying means 44 are formed as a coil extending in the toner conveying passage 36, where the winding direction of the coil 44 is such that when an end portion of the coil is rotated in said predetermined direction incident to the rotation of the rotating shaft, the coil is tensioned.
