    Abstract: A process comprises: (a) providing a migration imaging member (1) comprising: (1) a substrate (2) and (2) a softenable layer (6) comprising a softenable material (7) and a photosensitive migration marking material (8) in the layer as a monolayer of particles at or near the surface of the softenable layer (6) spaced from the substrate (2); (b) uniformly charging the imaging member (1); (c) imagewise exposing the charged imaging member to activating radiation at a wavelength to which the migration marking material (8) is sensitive; (d) causing the softenable material (7) to soften and enabling a first portion of the migration marking material (8) to migrate through the softenable material (7) toward the substrate (2) in an imagewise pattern while a second portion of the material remains unmigrated in the softenable layer (6); and (e) contacting the second portion of the migration marking material (8) with a transparency agent marking the material transparent.

    Abstract: A process for charging layered imaging members by the transfer of ions thereto from an ionically conductive medium. In one embodiment the process comprises contacting an ionically conductive liquid or polymer with the surface of the imaging member; and applying a voltage to the medium while moving the imaging member, thereby enabling the transfer of ions to said member.

    Abstract: A coated toner transport roll consisting of a core with a coating of charge transporting monomers (I) dispersed in a binder and an oxidising agent selected from ferric chloride and trifluoroacetic acid present in an amt. of 1-50, esp. 2-15 wt.%, the coating having a relaxation time of ca. 0.0099 millisecond to 3.5 milliseconds and a residual voltage of ca. 1-10 volts. Pref. the coating is 3-50 microns thick and the (I) is an aryldiamine of formula (I), in which X, Y and Z are H, 1-25C alkyl or halogen and at least one of X, Y and Z is independently chosen from alkyl and halogen, dispersed in a polyethercarbonate binder. Pref. the transport roll has a vol. electrical resistivity of ca. 10 power(9) ohm-cm to 10 power(11) ohm-cm and a dielectric constant of 3-5.
