Abstract
Imaging members useful in electrostatographic apparatuses, including printers, copiers, other reproductive devices, and digital apparatuses. More particularly, imaging members having nano polymeric gel particles embedded into one or more layers of the imaging member that provide for increased mechanical strength and improved wear.
Claims23
An imaging member, comprising:
- a substrate;
- a charge generating layer disposed on the substrate;
- a charge transport layer disposed on the charge generating layer;
- an overcoat layer disposed on the charge transport layer;
- an anti-curl back coating layer disposed on the substrate opposite to the charge transport layer;
- and
- a ground strip layer disposed on one edge of the imaging member,
- wherein the charge transport layer comprises a polycarbonate resin embedded with nano polymeric gel particles, and further wherein the nano polymeric particles comprise crosslinked polystyrene-n-butyl acrylate copolymers.
