Abstract

The presently disclosed embodiments relate generally to an image forming apparatus comprising a delivery member in contact with either the surface of an imaging member or in contact with the surface of the bias charge roller, wherein the delivery member is fabricated as a polymer matrix impregnated with functional materials, such that the functional material is transferred onto the imaging member or bias charge roller from the delivery member. Embodiments also pertain to an improved electrophotographic imaging member comprising a very thin outer layer on the imaging member surface, where the outer layer comprises functional materials, such as paraffin, that act as a lubricant and/or a barrier against moisture and/or surface contaminants. The improved imaging member exhibits improved xerographic performance, such as reduced torque, reduced friction, and deletions in high humidity conditions.
