Abstract
This invention relates to an improved organophotoreceptor that includes an electrically conductive substrate having a surface and a photoconductive element on said surface of said electrically conductive substrate. The photoconductive element comprises a layer with a polymeric binder, an electron transport compound, and a light stabilizer. The layer can also comprise a charge generating compound and/or a charge transport compound.
Claims21
An organophotoreceptor comprising an electrically conductive substrate having a surface and a photoconductive element on said surface of said electrically conductive substrate wherein said photoconductive element comprises a first layer comprising a polymeric binder, an electron transport compound and a UV light stabilizer.
An electrophotographic imaging apparatus comprising:
- (a) a light imaging component;
- and
- (b) an organophotoreceptor oriented to receive light from the light imaging component, the organophotoreceptor comprising an electrically conductive substrate having a surface and a photoconductive element on said surface of said electrically conductive substrate wherein said photoconductive element comprises a polymeric binder, an electron transport compound and a light stabilizer.
An electrophotographic imaging process comprising:
- (a) applying an electrical charge to a surface of an organophotoreceptor comprising an electrically conductive substrate having a surface and a photoconductive element on said surface of said electrically conductive substrate wherein said photoconductive element comprises a polymeric binder, an electron transport compound and a light stabilizer;
- (b) imagewise exposing said surface of said organophotoreceptor to radiation to dissipate charge in selected areas and thereby form a pattern of charged and uncharged areas on said surface;
- (c) contacting said surface with a toner to create a toned image;
- and
- (d) transferring said toned image to a receiving substrate.
