Abstract
A non-magnetic and non-contact AC development process has been numerically investigated using two-dimensional dynamic model. Simulation of toner dynamics in the development process was carried out using the Finite Difference Method (FDM) for the electric field calculation and the Distinct Element Method (DEM) for the calculation of charged toner motion in the electric field. Distribution of the electric charge density on a photoreceptor, the electrostatic latent image, was derived from a spot profile of a laser beam. Calculated results showed fairly good agreement with experiments.
