Xeroprinting processes employing imaged and developed migration imaging members as the xeroprinting master are known and disclosed in, for example, US. Patent 4,853,307, U.S. Patent 4,880,715, and U.S. Patent 4,883,731. Generally, the processes entail exposing to light a charged migration imaging member with a conductive layer and a layer of softenable material containing particles of a photosensitive material, followed by causing the softenable layer to soften by heating, exposure to solvent or vapor, or the like, resulting in migration of exposed particles toward the conductive layer. Optionally, the non-migrated particles can subsequently be caused to coalesce. The resulting imaging member can then be employed as a xeroprinting master by uniformly charging the master and flood exposing the member to light. Charge is selectively retained in relatively insulating areas of the imaging member where particles have migrated, and is discharged upon exposure to light in areas of the imaging member where particles have not migrated. The resulting charge pattern can then be toned and the toned image transferred to a substrate such as paper or transparency material.
