Abstract

In the ionographic process, ions are produced in corona chambers into which air is supplied at atmospheric pressure. Ordinarily corona is positive as it utilizes nitrogen, abundant in the air, to produce positive ions. The corona chamber and the orifice for ion output are necessarily small to obtain sufficient resolution of the latent image that will be produced with the ions on a charge retentive surface, and the ion output per pulse is limited.
