Mechanical and electrical robust imaging member and a process for producing same

A stress relief, flexible imaging member comprising:

• a substrate;
• an anti-curl back coating;
• an optional hole blocking layer;
• a charge generating layer;
• a charge transport layer;
• wherein said charge transport layer comprises from about 55 weight percent or more of an aromatic amine charge transport compound and a polymeric film forming resin;
• and,
• wherein the flexible imaging member is subjected to a heat treatment process to produce a stress relief, flexible imaging member.

A process for producing a stress relief, flexible imaging member web stock comprising:

• providing an imaging member web stock having at least a substrate layer and an outer charge transport layer, wherein the outer charge transport layer comprises from about 55 weight percent or more of an aromatic amine charge transport compound and a binder;
• transporting the imaging member web stock with the charge transport layer facing outwardly toward the surface of a circular treatment tube having an outer concave arcuate circumferential surface;
• passing the imaging member web stock over and making contact with the circular treatment tube having an outer concave arcuate circumferential surface to create a transverse web stock stretching force;
• heating instantaneously, while passing over the circular treatment tube, at least the charge transport layer of the web stock to a temperature above its glass transition temperature (Tg);
• and,
• cooling the charge transport layer of the web stock quickly subsequent to heating.
