Forces Acting on Carrier Iron Powder Adhering to Image Area in Developing Device

Abstract

This paper describes a macroscopic analysis of forces acting on carrier iron powder in the adhesive process of the electrophotographic development by magnetic brush method.
Applying the carrier iron powder model for magnetic brush development presented by R.M. Schaffert et al, on a macroscopic scale, the magnitude of forces acting on a carrier iron powder were computed from the physical circumstance produce by the developing magnet and the electrophotographic layer.
Carrier iron powders adhering to image area were suggested to deposit on toners by the coulomb attractive force due to the electrostatic latent image.
