Abstract
An electrophotographic imaging device includes a charging device, a cleaning device, and a fuser member that each include hydrophobic carbon nanotubes. The use of hydrophobic carbon nanotubes can increases the charging device's, the cleaning device's, and the fuser member's durability, conductivity, and contaminants deposition.
Claims6
An electrophotographic imaging apparatus comprising:
- a power supply;
- a photoreceptor;
- and
- a bias charging member comprising:
- a support substrate;
- a plurality of conductive coatings over the support substrate, wherein at least one of the plurality of conductive coatings comprises a plurality of hydrophobic carbon nanotubes in a resin or a polymer binder, and
- greater than 0% to less than 1% super hydrophobic carbon nanotubes,
- wherein the super hydrophobic carbon nanotubes have a water contact angle of greater than 120°, and
- wherein the bias charging member receives voltage from the power supply and charges a surface of the photoreceptor.
