Abstract

Disclosed is an imaging process for simultaneous printing of fixed and variable data which comprises, in the order states, (1) providing a migration imaging member comprising a substrate, a softenable layer comprising a softenable material and migration marking material contained at or near the surface of the softenable layer, and a charge transport material capable of transporting charges of one polarity; (2) uniformly charging the imaging member; (3) exposing the charged imaging member to activating radiation in an imagewise pattern corresponding to the fixed data, thereby forming an electrostatic latent image on the imaging member; (4) thereafter causing the softenable material to soften by the application of heat, thereby enabling the migration marking material exposed to radiation to migrate through the softenable material toward the substrate in an imagewise pattern corresponding to the fixed data; (5) uniformly charging the imaging member to the same polarity as the polarity of the charges that the charge transport material in the softenable layer is capable of transporting; (6) exposing the charged imaging member to activating radiation in an imagewise pattern corresponding to the variable data, thereby creating an electrostatic latent image on the imaging member corresponding to the variable data in areas of the imaging member wherein the migration marking material has not migrated; (7) uniformly charging the imaging member to the polarity opposite to the polarity of the charges that the charge transport material in the softenable layer is capable of transporting; (8) uniformly exposing the charged member to activating radiation, thereby forming an electrostatic latent image corresponding to both the fixed data and the variable data; (9) developing the electrostatic latent image; and (10) transferring the developed image to a receiver sheet.
