Abstract
A biasable transfer system member for use in an electrographic printing apparatus for attracting electrically charged particles from an imaging substrate to the biasable transfer system member includes an electrically conductive core and an outer layer of a fluorinated carbon filled elastomer wherein the fluorinated carbon has a fluorine content of about 10 to about 30 weight percent based on the weight of fluorinated carbon.
Claims27
A biasable transfer member comprising:
- a) an electrically conductive core;
- and
- b) an outer layer provided on said electrically conductive core comprising a fluorinated carbon-filled fluoroelastomer, wherein said fluorinated carbon has a fluorine content of from about 10 to about 30 weight percent based on the weight of fluorinated carbon, and the carbon content is from about 90 to about 70 weight percent.
A biasable transfer member comprising:
- a) an electrically conductive core;
- b) an outer layer provided on said electrically conductive core comprising a fluorinated carbon-filled fluoroelastomer, wherein said fluorinated carbon has a fluorine content of from about 10 to about 30 weight percent based on the weight of fluorinated carbon, and the carbon content is from about 90 to about 70 weight percent;
- and
- c) at least one intermediate layer positioned between said electrically conductive core and said outer layer;
- wherein the intermediate layer has a resistance of from about 10.sup.7 to about 10.sup.10 ohm-cm, and the outer layer has a resistance of from about 10.sup.7 to about 10.sup.12 ohm-cm.
A biasable transfer member comprising:
- a) an electrically conductive core;
- b) an outer layer provided on said electrically conductive core comprising a fluorinated carbon-filled fluoroelastomer, wherein said fluorinated carbon has a fluorine content of from about 10 to about 30 weight percent based on the weight of fluorinated carbon, and the carbon content is from about 90 to about 70 weight percent;
- and wherein said fluoroelastomer comprises a terpolymer of vinylidene fluoride, hexafluoropropylene and tetrafluoroethylene.
