Coronas and Gas Discharges in Electrophotography: A Review

The multitude of places where electrostatic phenomena occur in xerography are delineated. In at least one form or another, electrostatic phenomena occur in each and every step of the xerographic process. In some of these steps, many electrostatic phenomena occur simultaneously, and the situation is complicated by the fact that many of these phenomena are sensitive to ambient conditions. The relevant gas discharge phenomena are reviewed, and the underlying microscopic mechanisms are probed.
