ELECTRONIC IMAGING APPARATUS USING MULTICOLOR ELECTROPHOTOSENSITIVE PARTICLES

摘要

Electronically controlled imaging with a multicolor mixture of photoconductive particles is effected in a single exposure cycle by provision of an addressable electrode array which is energized selectively in imagewise timed relation. The control device for the imaging system has a plurality of sensing elements for measuring the color density values of successive lines of an original to be reproduced and producing a signal in response to the density measurement to regulate the length of time that the electrode array is energized.
