摘要： 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 located 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 eletrostatically charging the member, exposing the member to activating radiation in an imagewise pattern, decreasing the resistance to migration of marking material in the softenable layer sufficiently to allow the migration marking material struck by said activating radiation to retain a slight net charge which allows only slight agglomeration, slight coalescence, slight migration in depth of marking material towards said substrate or combination thereof in image configuration during a further decreasing of the resistance to migration towards the substrate in image configuration, and further decreasing the resistance to migration of marking material in the softenable layer sufficiently to allow non-exposed marking material to agglomerate and coalesce substantially. 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 surface potential associated with the surface charges of the latent image.

摘要： A process and apparatus for preparing migration imaging members are disclosed. Two substrates with softenable layers applied to them travel through a vacuum chamber where they are simultaneously exposed to vapor deposition of the migration marking material. After the migration marking material is deposited, the two softenable layers are laminated together in the same vacuum chamber to form the migration imaging member. In one of the embodiments, the softenable layers are applied to the substrates in the same sweep of the substrate through the vacuum chamber vapor deposition and lamination steps.

摘要： Disclosed is a xeroprinting process which comprises(1) providing a xeroprinting master comprising(a) a substrate; and(b) a softenable layer comprising a softenable material, a charge transport material capable of transporting charges of one polarity, and migration marking material situated contiguous to the surface of the softenable layer spaced from the substrate, wherein a portion of the migration marking material has migrated through the softenable layer toward the substrate in imagewise fashion;(2) uniformly charging the xeroprinting master to a polarity opposite to the polarity of the charges that the charge transport material in the softenable layer is capable of transporting;(3) uniformly exposing the charged master to activating radiation, thereby discharging those areas of the master wherein the migration marking material has migrated toward the substrate and forming an electrostatic latent image;(4) developing the electrostatic latent image; and(5) transferring the developed image to a receiver sheet.The process results in greatly enhanced contrast potentials or contrast voltages between the charged and uncharged areas of the master subsequent to exposure to activating radiation, and the charged master can be developed with either liquid developers or dry developers.
