摘要:
A bias transfer member or bias charging member for a xerographic device includes a support substrate, and a multi-layer conductive surface coating over the support substrate. The multi-layer coating includes a base layer of metal-containing particles in a polymer binder, an intermediate layer of conductive particles in a polymer binder, and a top layer of conductive particles in a polymer binder, wherein the amount of the conductive particles in the top layer is greater than the amount of the conductive particles in the intermediate layer. The multi-layer coating exhibits ideal electrical and abrasion resistance performance for use in bias charging or transfer members.

A donor member, useful in ionographic or electrophotographic apparatuses and preferably useful in hybrid scavengeless development units, has a substrate and an oxidized transport coating thereover. The oxidized transport coating includes a polymer binder, charge transporting molecules and one or more oxidizing agents. The polymer binder of the donor roll coating preferably includes one of (1) a crosslinked polymer with charge transporting molecules dispersed therein, or (2) a crosslinked polyamide binder with hydroxy charge transport molecules dispersed therein. The donor roll is preferably included in a printing machine that develops latent images formed on a photoconductive member.

A method for manufacturing a fibrillated pultruded electronic component includes the steps of providing a rod comprising a plurality of conductive fibers embedded in a matrix material, the rod having a first end and a second end. The rod is rotated and a liquid is sprayed onto the rod at a distance from the first end of the rod. The matrix material is abraded away from between the fibers of the rod. The fibers of the rod are then cut. A disk is formed which has a plurality of conductive fibers embedded in a matrix material. However, the ends of the disk include only the conductive fibers and not the matrix material. This enables the ends of the disk to have a fibrillated brush-like structure which is particularly well suited for low energy electronic/microelectronic signal level circuitry typified by contemporary digital and analog signal processors.

摘要:
In a xerographic printing apparatus, a scorotron places a uniform charge on a photoreceptor for forming electrostatic latent images. Three conductive pin arrays are disposed in a housing defined by sidewalls and a screen adjacent the photoreceptor. There can be provided insulative walls between adjacent pin arrays. The screen and a surface of the housing can be curved to correspond to a curvature of the photoreceptor.

In a module for use in a xerographic printer, a substantially single-piece device includes thereon a cleaning blade, seal flap, and side seals for engaging a photoreceptor. The device can be easily replaced when the module is remanufactured.
