| 摘要 |
An organic positive-charging photoconductor (+) OPC is disclosed. The (+) OPC has a conductive substrate; a hydroxy-containing binder component forming a layer greater than or equal to about 1 micron thick on said substrate; an X-type, metal-free phthalocyanine pigment component uniformly distributed throughout said binder component; and a reactive additive component selected from the list of cross-linkable resins, carboxlyic acid anhydrides, aldehydes, poly-ols, alkoxy silane coupling agents, reactive allyl polymers and dismaleimides, the reactive additive component also being uniformly distributed throughout, and being in cross-linked relation with, the hydroxy-containing binder component with an electron withdrawing functional group and an electron donating functional group in the same molecule. The (+) OPC, which may also contain a co-additive component, exhibits increased stability in a laser printing process.
