    摘要： The present embodiments are generally directed to an improved imaging member exhibiting various advantages over conventional imaging members. More specifically, the present embodiments are directed to an improved charge blocking layer formed from an aqueous-based coating solution which exhibits improved shelf life and coating properties, such as increased homogeneity and adhesion, and methods for making the same. The aqueous-based coating solution is environment-friendly and avoids the need to use more expensive organic solvents which involve higher safety risks in the manufacturing process.

    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.
