ABSTRACT:
Improved migration imaging techniques and apparatus utilizing a mixture of multicolor electrophotosensitive particles are achieved by exposure of the mixture, between electrodes which create a migration-inducing field, sequentially to the color separation components of the original image to be reproduced. Certain disclosed embodiments utilize exposure at spatially separated color sub-zones within an overall imaging zone to effect migration in controlled sequence, by particle type.
