  • Publication number: 20050031382
    Abstract: A developer sleeve for use in a monocomponent development system has a surface coating formed by an electric arc spray method. In one embodiment compressed air at a pressure of greater than 100 psi is used for driving the metal spray from the arc to the tube to be coated. In another embodiment, the developer sleeve is fabricated using mounting components of heat capacity and thermal conductivity both higher than that of the sleeve. In a still further embodiment, compressed air at a pressure of up to 100 psi is guided into the workpiece in order to dissipate heat from the interior of the workpiece. In a yet further embodiment, compressed air is used to aid disassembly of the sleeve from a mounting system following formation of the surface coating.

  • Patent number: 6470159
    Abstract: A process unit for use in an electrophotographic image forming apparatus includes a carrying handle, a photosensitive member, a process device and a moveable cover connected to the process unit and shielding an area of the periphery of the photosensitive member. The cover is designed to retract from its shielding position for the process unit and is installed into the body of the image forming apparatus. Retraction of the cover is preferably caused by the action of grasping the handle.

  • Patent number: 6418284
    Abstract: A service unit for an electrographic apparatus has a reservoir for storage of fresh toner or developer and a reservoir for storage of waste or depleted toner or developer. The fresh toner reservoir is separable from the waste toner reservoir and detachable from the service unit. The fresh toner reservoir has a wall which, in use, is in contact with a wall of the waste toner reservoir. Both contacting walls are flexible whereby the combined volume of the two reservoirs is less than the sum of the volumes which may be used to store the fresh and waste toner at different stages in the duty cycle of the service unit.

  • Patent number: 6091916
    Abstract: An electrophotographic image forming apparatus includes a removably mounted process unit containing a photosensitive member and process units. A movable cover is connected to the process unit and shields an area of a periphery of the photosensitive member. The movable cover is caused to retract from its shielding position in response to rotational movement of the photosensitive member.
