A photoconductor that includes, for example, a supporting substrate, an optional ground plane layer, an optional hole blocking layer, an optional adhesive layer, a photogenerating layer, and a charge transport layer, and where the charge transport layer contains a mixture of a charge transport component and a polycarbonate AP.

Polycarbonate containing photoconductors

Embodiments pertain to a novel imaging member, namely, an imaging member or photoreceptor comprising an overcoat layer which comprises a soluble filler that improves low surface energy and wear. The soluble filler is a silicone poly(ethylene glycol) ester which improves low surface energy and wear without negatively impacting electrical properties of the overcoat layer.

Cross-linked overcoat layer

Embodiments pertain to a novel imaging member, namely, an imaging member or photoreceptor comprising a binderless overcoat layer which exhibits substantially improved electrical performance, such as low residual potential and good electrical cyclic stability. The overcoat layer of the present embodiments is formed from a formulation comprising a small transport molecule, a crosslinking agent, an acid catalyst and a solvent.
