Abstract
An aggregate-type xerographic photoconductor wherein primary or secondary amines are used not only to solubilize the photoconductor's light sensitive organic dye, but also to act as a cross-linker for an epoxy binder of the bisphenol class. A combined CTL/CGL layer is described, having both hole transport and charge generating dye molecules. The resulting layer is useful either as single-layer, bimodal photoconductor, or as the CGL of a two-layer photoconductor.
