Abstract
The present teachings provide a fuser system for use in a xerographic apparatus. The fuser system includes a fuser roller and a pressure roller. The fuser roller and the pressure roller create a nip. The fuser roller has an outer layer of carbon nanotubes dispersed in a fluoropolymer wherein the carbon nanotubes comprise from about 0.1 weight percent to about 10 weight percent of the outer layer. The pressure roller comprises a static dissipative outer surface having a surface resistivity of less than about 1010 Ω/cm.
Claims19
A fuser system comprising:
- a fuser roller comprising an outer layer comprising carbon nanotubes dispersed in a fluoropolymer wherein the carbon nanotubes comprise from about 0.1 weight percent to about 10 weight percent of the outer layer
- an oil delivery roller in contact with the outer layer of the fuser roller for delivering oil, wherein the oil delivery roller comprises a static dissipative outer surface having a surface resistivity of less than about 1010 Ω/cm;
- and
- a pressure roller wherein the fuser roller and the pressure roller create a nip, the pressure roller comprising a static dissipative outer surface having a surface resistivity of less than about 1010 Ω/cm.
An image forming apparatus for forming images on a recording medium comprising a charge-retentive surface to receive an electrostatic latent image thereon;
- a development component to apply toner particles to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface;
- a transfer component to transfer the developed image from the charge retentive surface to a copy substrate;
- and a fuser system for fusing toner particles to the copy substrate, wherein said fuser system comprises:
- a fuser roller comprising a release layer comprising carbon nanotubes dispersed in a fluoropolymer wherein the carbon nanotubes comprise from about 0.1 weight percent to about 10 weight percent of the release layer;
- an oil delivery roller in contact with the release layer of the fuser roller for delivering oil, wherein the oil delivery roller comprises a static dissipative outer surface having a surface resistivity of less than about 1010 Ω/cm;
- and
- a pressure roller comprising a static dissipative outer surface having a surface resistivity of less than about 1010 Ω/cm wherein the fuser roller and the pressure roller create a nip through which the copy substrate passes.
A fuser system comprising:
- a fuser roller comprising a release layer comprising carbon nanotubes dispersed in a fluoropolymer wherein the carbon nanotubes comprise from about 0.1 weight percent to about 10 weight percent of the outer layer;
- an oil delivery roller for delivering oil to the release layer of the fuser roller wherein the delivery roller comprises a static dissipative outer surface having a surface resistivity of less than about 106 Ω/cm;
- and
- a pressure roller wherein the fuser roller and the pressure roller create a nip, the pressure roller comprising a static dissipative outer surface having a surface resistivity of less than about 106 Ω/cm.
