摘要: 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.

摘要: Disclosed are undercoat layers comprising a metal oxide, a polymer, and a citrate of Formula (I): wherein R1 is H, alkyl, or COR′; wherein R′ is alkyl; and wherein R2, R3, and R4 are 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.

摘要: The disclosed embodiments are directed to a method for removing photoreceptor coatings from a rigid substrate, wherein the photoreceptor coatings disposed over a substrate of an electrophotographic photoreceptor, in order to recover it for re-use in photoreceptor manufacturing. More specifically, the invention discloses a photoreceptor substrate recovery methodology that includes the creation of an inner release layer over the substrate and followed by subjecting the rejected or used electrophotographic photoreceptor to a step of soaking in a non-toxic and environmentally-friendly stripping solution that separates the coatings from the substrate.
