  Analytical Modeling of Electrostatic Toner Adhesion

  Analytical Modeling of Electrostatic Toner Adhesion

  By applying an analytical model of charged dielectric particle interactions

  the physics of attachment and detachment in an applied static field is analyzed. It is shown that differences between electric field detachment and mechanical detachment

  as reported from prior experiments

  have fundamental theoretical basis. Described physics includes a maximum electrostatic detaching force

  the enhancement in adhesion force due to particle polarization

  the effective reduction in detachment force in a detaching electrostatic field

  and the ineffectiveness of an applied field to detach weakly charged particles. Additionally

  closed-form equations are provided for approximate calculations of the physical effects.
