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.

摘要： An imaging member having a charge transport layer is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein the upper or additional transport layer(s) comprise a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be the same or different from that included in the additional charge transport layers. The charge transport compound in one or more of the layers is dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.
