PHOTORECEPTOR OUTER LAYER
First Claim
Patent Images
1. An imaging member comprising:
- a substrate;
a photosensitive layer disposed on the substrate; and
an outer layer disposed on the photosensitive layer, wherein the outer layer of the imaging member has a patterned surface comprising an array of periodically ordered indentations or protrusions on the surface of the outer layer.

Abstract
The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrophotographic, including digital, apparatuses. Embodiments pertain to an improved electrophotographic imaging member incorporating an outer layer having a nano- to micron-scale pattern imprinted into its surface to lower friction with the cleaning blade and improve print quality and performance. Embodiments also pertain to methods for making the improved imaging member.
