摘要:
A toner crushing wire is disposed in a cleansing housing (25) so as to extend along a rotating shaft of the cleaning roller (27). The toner crushing wire (30) is allowed to swing along a cleaning housing inner wall facing the peripheral surface of the cleaning roller (27) in non-contact with the cleaning housing inner wall. In this way, remaining toner scraped off from the peripheral surface of a photosensitive drum (11) by a cleaning blade (26) is crushed by the toner crushing wire (30).

摘要:
An image forming apparatus includes an image carrier configured to carry an image on a surface thereof, a cleaning unit including a cleaning blade and configured to remove residual toner remaining on the surface of the image carrier with the cleaning blade, and an application unit including a brush roller having a modified cross-section fiber and configured to use the brush roller to scrape molded lubricant into scraped lubricant and apply the scraped lubricant to the image carrier. A process cartridge is provided to the image forming apparatus and integrally includes the image carrier, the cleaning unit, the application unit, and at least one of a charging unit and a developing unit in a single unit.
摘要:
An image forming apparatus of the present invention includes at least one process cartridge removably mounted on the apparatus body and including at least an image carrier (2) on which a toner image is to be formed and a cleaning device (13) configured to remove toner left on image transfer with a cleaning blade. A hole (69,44) for passing a light beam emitted from an optical writing unit (8) toward the image carrier therethrough is formed in part of the case bottom wall of the process cartridge higher in level than part of the case bottom wall below the cleaning blade.
摘要:
A channel (130) for recirculating a stream of air (116) located adjacent a stream of marking particles exiting substantially tangentially from a marking particle transport member (90) within a developer unit is provided. The stream of marking particles defines an inner boundary (110) thereof extending tangentially from a first position (106) adjacent to the transport member (90) and an outer boundary (112) thereof spaced from the transport member (90) and the inner boundary (110). The channel includes a first member (136) positioned outside the stream of marking particles. At least a portion of the first member (136) is positioned substantially adjacent the outer boundary (112) and spaced from the transport member (90). The channel also includes a second member (140) connected to the first member (136) and a third member (142) connected to the second member (140). Substantially all the stream of air being directed by the first member (136) is sequentially directed by the second member (140) and the third member (142).
摘要:
There is provided a cleaning unit for removing residual toner present on the periphery of a photoconductive drum (42) after toner image transfer, which includes: a main blade (105) for scraping the toner from the surface of the photoconductive drum (42); and a cleaning roller (107) disposed below the main blade (105) and abutting against the periphery of the photoconductive drum (42). The inner space of the cleaning housing (101) is divided into a cleaning chamber (103) and a toner storage (104) by a separator plate (102). A spacing (S) between the lower end (102a) of the separator plate (102) and the periphery of the cleaning roller (107) is adjusted to preferably 1mm to 2mm, more preferably 1.3mm to 1.5mm. By thus adjusting the spacing (S), the toner is compressed when passing through the spacing and, hence, the toner transportation pressure is increased.
摘要:
A developing device used in an electrophotographic apparatus has seal members (60) fixedly disposed between both end portions of a developing roller (31) and those portions of inner walls of a device casing (21) which correspond to both end portions of the developing roller (31). The seal members (60) are made of a material which can be charged by friction with the developing roller (31) to have the same polarity as charged toner. The toner is blocked by the seal members (60) and prevented from entering end portions of the developing roller (31).
