More Information
Summary:The present invention relates generally to electrophotographic imaging members. The invention relates particularly to electrophotographic imaging members in which crystallization of charge transport molecules is eliminated or minimized. An electrophotographic imaging member comprises a substrate, a charge generating layer, and a charge transport layer. The charge transport layer comprises a binder and charge transport molecules, wherein the binder eliminates or minimizes crystallization of the charge transport molecules. Optionally, an electrophotographic imaging member comprises a substrate and a single charge generating and charge transport layer. The single charge generating and charge transport layer comprises a binder, charge generating molecules and charge transport molecules, wherein the binder eliminates or minimizes crystallization of the charge transport molecules. Specific binders are PCZ-800, a PCZ-500, or a PCZ-400 polycarbonate resin.
