摘要： An electrostatographic printer has a process unit adapted to be removably mounted in a main assembly of an electrostatographic reproducing machine, the process unit including a developement apparatus at which an electrostatic latent image is developed on an imaging member, and a transfer device which causes a developed toner image to be transferred from the moving imaging member to a copy sheet. The development apparatus is contained within a housing of an electrically insulating material, and comprises conductive means adjacent the exit portion of the development apparatus, i.e. the portion from which the imaging member emerges as it moves towards the transfer device. The conductive means includes a conductive coating on the exit portion of the developer housing, and a conductive seal member through which an electrical discharge path is provided. This reduces the tendency of debris to accumulate in the region of the exit portion, and prevents any debris which does accumulate from building up a charge (which would have detrimental effects on the developed image).

摘要： An apparatus in which an electrostatic latent image recorded on a photoconductive member is developed. A supply of developer material comprising at least toner particles and carrier granules is stored and transported closely adjacent to the electrostatic latent image recorded on the photoconductive member. The quantity of developer material being transported to the electrostatic latent image recorded on the photoconductive member is controlled by a metering blade. At least accumulation of toner particles adjacent the blade is prevented and a flow of toner particles away from the blade induced. In this way, the escape of toner particles from the storage chamber thereof is substantially minimized.This invention relates generally to an electrophotographic printing machine, and more particularly to a development system which minimizes the escape of at least the toner particles of the developer material therefrom.In a typical electrophotographic printing machine, a photoconductive member is charged to a substantially uniform potential to sensitize the surface thereof. The charged portion of the photoconductive surface is exposed to a light image of an original document being reproduced. This records an electrostatic latent image on the photoconductive member corresponding to the informational areas contained within the original document. After the electrostatic latent image is recorded on the photoconductive member, the latent image is developed by bringing a developer material into contact therewith. This forms a powder image on the photoconductive member which is subsequently transferred to a copy sheet. Finally, the copy sheet is heated to permanently affix the powder image thereto in image configuration.Generally, the developer material is made from a mixture of carrier granules and toner particles. The toner particles adhere triboelectrically to the carrier granules. This two-component mixture is brought into contact with the latent image. Toner particles are attracted from the carrier granules to the latent image forming a powder image thereof. Hereinbefore, the toner particles contained within the development system frequently escaped therefrom resulting in contamination of the printing machine. This produced degradation of copy quality and frequently resulted in excessive service calls. Moreover, the environment surrounding the various processing stations within the printing machine would invariably become dirty or coated with particles. In the development system, a magnetic brush developer roller transports developer material closely adjacent to the photoconductive surface. A metering blade regulates the thickness of the layer of developer material adhering to the developer roller. It has been found that a fairly thick layer of toner particles forms on the metering blade. The accumulation of toner particles on the metering blade provides a source thereof at least a part of which may escape from the development system resulting in contamination of the surrounding subassemblies within the printing machine.Various techniques have been devised for preventing the escape of toner particles from the development system. The following disclosures appear to be relevant:U.S. Pat. No. 3,098,765; Patentee: Keller et al.; Issued: July 23, 1963.U.S. Pat.

No. 1,052,019; Patentee: Lawes; Published: Dec. 21, 1966.The pertinent portions of the foregoing disclosures may be briefly summarized as follows:Keller et al. and Mikolas describe metering blades for regulating the thickness of developer material adhering to a developer roller used in a magnetic brush development system.Kutsuwada et al. discloses a development station wherein a developer roller transports particles to a latent image recorded on a photoconductive member. A fan maintains a negative pressure within the development station so as to prevent particles from escaping therefrom. A filter catches any scattered particles to prevent them from escaping the development system.Swanson et al. discloses a copying machine having a particle conveying system including a plurality of pneumatic ducts and a blower. A vacuum-type pickup device is attached to the blower and positioned to remove loose particles from the copy sheets exiting the machine. The pneumatic system includes a centrifugal separator to receive the particles from the vacuum pickup. The centrifugal separator separates the particles from the air and collects the particles in the chamber for subsequent re-use. The air exiting the separator passes through a filter prior to returning to the atmosphere.Bell describes a system for reclaiming residual toner particles removed from a photoreceptor. A blower removes air and toner from a photoreceptor cleaner. The toner is separated from the moving air and stored for re-use with the clean air being vented to the atmosphere.Jugle describes a development system having a filter disposed in a wall thereof and a vacuum system associated therewith for maintaining the chamber of a development system at a negative pressure to prevent the escape of particles therefrom. The developer material flows over the filter and cleans particles therefrom.Lawes discloses a photoreceptor cleaning system having brush rollers for removing the residue of powder images from the photoreceptor. The dust laden air is driven by a fan through a filter or electrostatic precipitator from which the dust may be recovered.In accordance with one aspect of the features of the present invention, there is provided an apparatus for developing an electrostatic latent image recorded on a photoconductive member. Means, defining a chamber, store a supply of developer material comprising at least carrier granules and toner particles therein. Means, disposed in the chamber of the storing means, transport developer material closely adjacent to the electrostatic latent image recorded on the photoconductive member. Means control the quantity of developer material being transported by the transporting means to the electrostatic latent image recorded on the photoconductive member. Means prevent the accumulation of at least the toner particles adjacent the controlling means and induce a flow of toner particles away from the controlling means.Pursuant to another aspect of the present invention, there is provided an electrophotographic printing machine of the type having an electrostatic latent image recorded on a photoconductive member. Means, defining a chamber, are provided for storing a supply of developer material comprising at least carrier granules and toner particles therein. Means, disposed in the chamber of the storing means, transport the developer material closely adjacent to the electrostatic latent image recorded on the photoconductive member. Means control the quantity of developer being transported by the transporting means to the electrostatic latent image recorded on the photoconductive member. Means prevent the accumulation of at least the toner particles adjacent the controlling means and induce a flow of toner particles away from the controlling means.
