Electrostatographic machine with screening

摘要

Each region of a photoconductive member receives an electrostatic charge over a predetermined time period. An electrostatic latent half-tone pattern image is screened on the photoconductive member such that exposure of the photoconductive member to a light pattern of a continuous tone original document will form a half-tone latent image on the photoconductive member. The screened image is formed during the predetermined time period that each region of the photoconductive member is being charged such that the half-tone pattern is partially charged over.
