摘要： An apparatus which develops an electrostatic latent image recorded on a photoconductive member with toner particles. A donor member is spaced from the photoconductive member and transports toner particles to a development zone adjacent the photoconductive member. Electrode wires are positioned in the development zone between the photoconductive member and the donor member. The electrode wires are electrically biased to detach toner particles from the donor member to form a cloud of toner particles in the development zone. Toner particles detached from the toner particle cloud develop the latent image. The electrode wires are adjustably supported in tension adjacent the donor member.

摘要： In a development system for conveying toner to a latent image on a surface in an electrophotographic printing apparatus, including a donor structure spaced from the charge retentive surface for conveying toner to a development zone adjacent the surface and an electrode structure disposed between the donor structure and the surface, contaminants are removed from the development zone by a flow of air away from the development zone.

摘要： An apparatus for supporting wires in a wire module for use in a scavengeless development system using wire maintaining members that longitudinally support the wires. The tops of the wire maintaining members have grooves that positively position the wires and set a desired wire to wire spacing. The wire maintaining members are integral with the wire module and are part of a wire tensioning system. The wire maintaining members are part of an assembly that allow the wires to be pretensioned to the operable development tension prior to the wire module being mounted to the developer housing. The wire maintaining members also have a unique mounting system which allows the wire module to be rotatably mounted to the developer housing.

摘要： In a multi-color imaging apparatus, the voltage differential between developed and undeveloped areas of a charge retentive surface is reduced for precluding edge effect development. The developed areas correspond to charged areas on the photoreceptor while the undeveloped areas represent discharged or background areas on the photoreceptor. Development of the charged areas is followed by an erase step for reducing the voltage differential between the developed areas and the non-developed background areas prior to the next development step.

摘要： In a multi-color imaging apparatus utilizing a recharge step between two image creation steps for conditioning a charge retentive surface pursuant to forming the second of the two images, a voltage sensitive corona generating device having a high characteristic slope described in a graph of the current delivered to a charge receiving surface (I) vs. grid minus charge receiving surface voltage (V) is used to both reduce the residual toner voltage across the previously toned image, and to charge the toned and untoned areas of the charge retentive surface to a substantially uniform level so that developability conditions for the subsequent image are improved.

摘要： A multicolor electrophotographic printing machine employing a plurality of developer units. Each of the developer units is actuated to develop a selected latent image with the appropriately colored toner particles. The other developer units are de-energized. In the development mode, the electrode wires and the donor roll are electrically biased to suitable voltages. In the non-development mode, the electrode wires have only a DC voltage applied thereon with the AC voltage being turned off. Substantially, simultaneously therewith, the electrical bias on the donor roll is adjusted to prevent further development. In this way, the developer unit does not develop a latent image in the non-operable mode and does not attract toner particles thereto from the latent image.

摘要： Fixing devices including extended-life components and methods of fixing marking material to a substrate are provided. An exemplary embodiment of the fixing devices for fixing toner to a substrate in printing includes a first fixing member including a first surface; a thermal energy source for heating the first surface of the first fixing member to a fixing temperature; and a second fixing member including a second surface. The first surface and the second surface form a fixing nip configured to receive a substrate including a surface and marking material comprising toner disposed on the surface. The first fixing member and the second fixing member are operable to apply a pressure of at least about 300 psi to the substrate and toner and to heat the toner to a sufficiently-high temperature, at the fixing nip, to fix the toner to the substrate.

摘要： A method and apparatus transfer a material from first roller within a container to at least one second roller, and transfer the material from the second roller to at least one third roller. The second roller and the third roller form a loading nip at a location where the second roller is closest to the third roller. The method and apparatus transfer the material from the third roller to at least one recipient device, and measure current flow between the second roller and the third roller using a measurement device. Then, the method alters the relative rotation rate difference between the first roller and the second roller based on the current flow to maintain a predetermined density of the material at the loading nip using a controller.
