Abstract

A basic advantage of xerographic powder cloud development is that very small voltage variations residing on a photoreceptor surface can be resolved by development, however, only a narrow input density variation can be resolved at any given input exposure, Where input subjects have a wide density variation, therefore, it is usually necessary to select a particular density input interval and to bias the development system accordingly. It is found, possible for xeroradiographic or similar purposes, however, to increase copy density range by employing multiple color toners, each toner being utilized at a different charge level to record the particular bone or tissue details desired.
