Abstract

The presently disclosed embodiments are directed to charge transport layers useful in electrostatography. More particularly, the embodiments pertain to an improved electrostatographic imaging member having a charge transport layer that is dual-dopant, wherein operating life improvement is achieved by incorporating a small amount of compatible thermalsetting resin and polyhedral oligomeric silsesquioxane into the layer. Incorporation of these resins have been shown to increase charge transport life.
