Adhesion of Silica-Coated Toner Particles to Bisphenol-A Polycarbonate Films
  DOI :  10.2352/J.ImagingSci.Technol.(2008)52:1(010503)  Published OnlineJanuary 2008

Particles of electrophotographic toner (black, silica-coated, number-weighted diameter of 7 μm) were electrostatically developed on the surface of a film of bisphenol-A polycarbonate coated on nickelized polyethylene terephthalate (PET). The thickness of the coatings varied from 0.8 to 22.0 μm. The force needed to remove the particles was determined using ultracentrifugation. We found that removal of half of the particles from the film surface required a force of approximately 250 nN irrespective of the thickness of the polymer film. This result indicates that removal of the toner from the film involves surface van der Waals interactions rather than forces associated with long-range electrostatic interactions of the charged toner with the grounded nickel electrode.
