Disclosed are undercoat layers comprising a metal oxide, a polymer, and a citrate of Formula (I): wherein Ris H, alkyl, or COR'; wherein R&#x2032; is alkyl; and wherein R, R, and Rare independently alkyl. The undercoat layers are useful in imaging members because they are easily separated from the substrate. This reduces the number of steps necessary to reclaim the substrate.

Embodiments relate generally to an imaging member that facilitates removal of the imaging member coating layers disposed over the imaging member and environmentally or 'green' methods for using the same. More specifically, the present embodiments disclose an electrophotographic photoreceptor that includes a specifically formulated undercoat layer that allows easy removal of the photoreceptor layers disposed on top of the undercoat layer. The present embodiments provide a simple yet efficient method for reclaiming recycling or remanufacturing electrophotographic photoreceptors.

Releasable undercoat layer and methods for using the same

The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrophotographic, including digital, apparatuses. In particular, the present embodiments pertain to an improved imaging member comprising a single layer in which the single layer further comprises a combination of one or more high mobility hole (charge) transport molecules and electron transport molecules.
