A developing device includes a toner cartridge mounting portion, and a toner cartridge to be detachably mounted on the toner cartridge mounting portion. The toner cartridge mounting portion has a bottom wall having a toner acceptance opening formed therein, and a pair of supporting side walls disposed on the opposite side edges of the bottom wall, and an engaging means is disposed on the inner surface of one of the supporting side walls. The toner cartridge includes a generally cylindrical container having an unsealably sealed toner discharge opening formed in the peripheral wall of the container, and a toner accommodated in the container. An engaged means to be engaged with the engaging means is disposed in the outer surface of one side wall of the container. The one side wall of the container is opposed to the inner surface of the one of the supporting side walls to engage the engaging means and the engaged means with each other, and the other side wall of the container is opposed to the inner surface of the other of the pair of supporting side walls, whereby the toner cartridge is mounted on the toner cartridge mounting portion.

An image-forming machine equipped with a transfer means (30) of the type not using a transfer corona discharger is disclosed. A charge supply member (38) is disposed opposite to an image forming member (4) on whose surface a toner image is to be formed and at a greater distance (D) than the thickness of a transfer material (26) from the image forming member (4). In a transfer zone (12), the surface of the transfer material (26) is brought into contact with the surface of the image forming member (4). In a charge supply zone (46), the transfer material (26) is contacted with the surface of the charge supply member (38). In the direction of conveyance of the transfer material (26), the charge supply zone (46) is positioned downstream of the transfer zone (12).

A corona discharging device (1) in which an engaging member (11) engaging with one of slits (23) of a control grid (20) is provided on a cover (6) of one end block (3) provided in a case (2). When mounting the control grid (20) on the corona discharging device (1), one end of the control grid (20) is at first attached to the device, and the slit (23) formed in the other end of the control grid (20) is engaged with the engaging member (11) on the cover (6). Subsequently, the cover (6) is mounted on the end block (3) with its one end serving as a fulcrum.
摘要:
An area setting device for setting coordinates of two points in diagonal direction of one or more number of areas by sequential key operations. Different colors are used for coordinates display (53, 53x, 53y) by each direction, the same colors as coordinates display are used for coordinates input indicator (52). Memorizing means (62, 63) memorize all the points as coordinates input condition or coordinates non-input condition, whereby the key input is accepted to the point of the highest order of all the points of coordinates non-input condition, and converted into memorized condition as the point of coordinates input condition. Then key input acceptance and memory state conversion are repeated for coordinates input of the points required.
摘要:
A latent electrostatic image developing device of an image forming machine, comprising a developing roller (53) disposed in a development housing (51) for applying in a developing zone a developer to a latent electrostatic image formed on a photoconductor drum (42), a makeup roller (54) for supplying a developer to the peripheral surface of the developing roller (53) in a developer holding zone, and a developer regulating means (56) for regulating the amount of the developer, held on the peripheral surface of the developing roller (53), in a developer regulating zone. The developing roller (53) is rotationally driven from below to above in the developing zone. The developing roller (53) and the makeup roller (54) are both rotationally driven from above to below in the developer holding zone. The developer regulating means (56) is disposed below the developing roller (53).

An image-forming machine equipped with a transfer means (32) of the type not using a transfer corona discharger is disclosed. A charge supply member (52) is disposed opposite to an image forming member (6) on whose surface a toner image is to be formed, and at a greater distance than the thickness of a transfer material (28) from the image forming member (6). A voltage of a predetermined polarity is applied to the charge supply member (52). In a transfer zone (14), the surface of the transfer material (28) is brought into contact with the surface of the image forming member (6), while the back of the transfer material (28) is not contacted with the surface of the charge supply member (52).
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).
