Embodiments pertain to a novel imaging member, namely, an imaging member or photoreceptor comprising a protective outer layer which comprises light-absorbing composition that substantially prevents any light absorption by the overcoat layer. The composition comprises a low strength thermal plastic resin and a high optical density yellow dye. Thus, the light-blocking protective layer reduces the intrinsic light shock suffered by conventional overcoat layers without negatively impacting electrical properties of the overcoat layer and while improving print quality.

Protective photoreceptor outer layer

The presently disclosed embodiments are directed generally to an improved electrostatographic imaging member in which the overcoat layer comprises cross-linkable polyester resins. The overcoat layer not only provides wear resistance, but it also provides higher charge transport efficiency and therefore better photoelectrical properties. In addition, the polyesters can cross-link with a variety of resins and thus provide good adhesion as well.

Polyester-based photoreceptor overcoat layer

A photoconductor that includes a supporting substrate, an optional ground plane layer, an optional hole blocking layer, a photogenerating layer, and at least one charge transport layer, and where the charge transport layer contains a polyalkylene glycol benzoate.

Polyalkylene glycol benzoate containing photoconductors

A photoconductor that includes, for example, a substrate, an undercoat layer thereover wherein the undercoat layer contains a metal oxide dispersed in a mixture of a sulfonamide formaldehyde resin and a phenolic formaldehyde resin; a photogenerating layer, and at least one charge transport layer.
