Abstract

An imaging system in which an imaging member comprising a substrate and an electrically insulating softenable layer on the substrate, the softenable layer comprising migration marking material locked at least at or near the surface of the softenable layer spaced from the substrate, and a charge transport material in the softenable layer is imaged by electrostatically charging the member, exposing the member to activating radiation in an imagewise pattern, and decreasing the resistance to migration of marking material in the softenable layer sufficiently to allow the migration marking material struck by activating radiation to substantially migrate in depth towards the substrate in image configuration. This imaged member may be used as a xeroprinting master in a xeroprinting process comprising uniformly charging the master, uniformly exposing the charged master to activating illumination to form an electrostatic latent image, developing the latent image to form a toner image and transfering the toner image to a receiving member. A charge transport spacing layer comprising a film forming binder and a charge transport compound may be employed between the substrate and the softenable layer in order to increase the contrast potential associated with the surface changes of the latent image.
