Exemplary embodiments provide materials and methods for an electrostatic charging member including a conductive substrate; a base layer disposed over the conductive substrate, the base layer comprising an elastomeric material and a semiconductive material; and a protective outer layer disposed over the base layer, the protective outer layer comprising a polymeric resin and a plurality of conductive particles, wherein the outer protective layer has a surface resistivity ranging from about 10O/sq to about 10O/sq.

Protective coatings for bias charge rollers

Provide herein is a description of a bias charging member that includes a conductive core, and an outer surface layer disposed on the conductive core. The outer surface layer includes carbon black and acrylonitrile-butadiene-styrene.

Bias charging overcoat

Various embodiments provide materials and methods for bias charging members including an outer surface coating, wherein the outer surface coating can include carbon nanotubes combined with polymer(s) to provide desirable surface, electrical, and/or mechanical properties.

Bias charge roller surface coating comprised of carbon nanotubes

Provide herein is a bias charging member that includes a conductive core, and an outer surface layer disposed on the conductive core. The outer surface layer includes carbon black and polycarbonate.

There is described a bias charging member that includes a conductive core and an outer surface layer on the conductive core. The outer surface layer includes a resin of aminoplast and one of polyol or nylon, a conductive additive and p-toluene sulfonic acid. There is also described a method of refurbishing bias charging members.

Disclosed are bias charge rollers having an overcoat layer. The overcoat layer comprises an acrylonitrile-butadiene-styrene (ABS) terpolymer and metal oxide particles optionally doped with a doping agent. The resulting bias charge rollers have reduced streaking and increased service lifetimes.

Bias charge roller comprising overcoat layer

Disclosed are bias charge rollers having an overcoat layer. The overcoat layer comprises a phenolic resin and a conductive agent. The resulting bias charge rollers have reduced streaking and increased service lifetimes.

This is a shroud for housing a replacement photoconductive drum. The shroud has an open gap at its top portion and this gap is covered by at least two overlapping flexible strips that are configured to allow a handle structure to pass therethrough on its way to an exit in the shroud where the photoconductive drum is pushed out of the shroud when installing the drum in a marking machine.
