Claims
- 1. A coated toner transport roll consisting essentially of a core consisting essentially of a conductive material with a coating thereover containing a partially oxidized charge transporting polymer or consisting essentially of an insulative dielectric material with a coating thereover of a partially oxidized charge transporting polymer; wherein the charge transporting coating is a carbonate of the formula wherein n is a number of from about 10 to about 1,000; and wherein and wherein the said carbonate is oxidized with trifluoroacetic acid.
- 2. A coated toner transport roll consisting essentially of a core consisting essentially of a conductive material with a coating thereover containing a partially oxidized charge transporting polymer or consisting essentially of an insulative dielectric material with a coating thereover of a partially oxidized charge transporting polymer; and wherein the charge transporting polymer is oxidized with ferric chloride.
- 3. A coated toner transport roll consisting essentially of a core consisting essentially of a conductive material with a coating thereover containing a partially oxidized charge transporting polymer or consisting essentially of an insulative dielectric material with a coating thereover of a partially oxidized charge transporting polymer; and wherein the core is a metal, and which core comprises first and second interdigitated electrodes.
- 4. A coated toner transport roll consisting of a core consisting of a conductive material with a coating thereover containing a oxidized charge transporting polymer or consisting of an insulative dielectric material with a coating thereover of a partially oxidized charge transporting polymer.
- 5. A xerographic toner transport roll consisting of a metal core containing first and second electrodes, and wherein said metal core consists of a conductive component with a coating thereover of an oxidized charged transporting polymer.
- 6. A transport roll in accordance with claim 5 wherein the conductive component is a metal.
