    摘要: The present disclosure is related to coated photoconductors. In an example, a coated photoconductor can comprise a photoconductor including a substrate having a charge generation layer and charge transport layer adhered thereto and a top coating adhered to the photoconductor. The top coating can comprise a cross-linkable polymer, a cross-linker, and a polymeric dopant having a weight average molecular weight of less than 500,000. Additionally, the top coating can have a thickness of 0.1 μm to 12 μm and the polymeric dopant can be present in the top coating at a concentration of 0.1 wt % to 10 wt %.
