Abstract: In a cleaning arrangement for the removal of residual toner from a charge retentive surface, such as a photoreceptor surface in a reproduction machine, after a transfer step, a conductive cleaning member is arranged closely adjacent the surface. An A.C. voltage is applied to the member. In such an arrangement, toner in the vicinity of the blade is observed to jump from the surface in response to the electric field created at the member, forming an oscillating toner cloud. The agitated toner further aids in removal of toner from the surface by causing a large number of toner/toner impacts that jar toner held on the surface into movement. Toner held on the surface is thus removed electrostatically and mechanically. Toner in the cloud configuration may be easily removed from the area adjacent the surface by an airstream through the area, a biased collecting surface, or a traveling electrostatic wave arrangement, among other methods.

Abstract: A migration imaging system wherein an imaging member comprising migration marking material contained in or contacting a softenable layer on a supporting substrate has a latent image formed thereon, and the latently imaged member is developed by passing it through one or more small meniscuses bonding at least in part a volume of liquid which is capable of changing the resistance of the softenable material, to migration of the migration marking material toward the substrate. Alternately, an imaged migration type imaging member, having marking material in a migrated image comfiguration and in a background configuration which is at least in part spaced apart in depth in the softenable layer from said image configuration, is further developed by the inventive system.

Abstract: A migration layer comprising migration material and softenable material, said migration layer having a set electrical latent image. The process of setting the electrical latent image comprises providing an imaging member comprising the above migration layer, electrically latently imaging the migration layer and setting the electrical latent image by either storing the migration layer in the dark or applying heat, applying vapor, or applying partial solvents in a pre-development softening step. After setting of the electrical latent image, the migration layer can be exposed to activating electromagnetic radiation without loss of the latent image and permitted long delays of up to years between formation of the electrical latent image and the development step which allow selective migration in depth.

Abstract: An imaging system using a migration imaging member comprising a softenable photoconductive material with a fracturable layer of migration marking material contacting the softenable photoconductive material and having the fracturable layer spaced apart from at least one surface of the softenable layer and typically contiguous to the free surface of the softenable material. Imaging with a member comprising a softenable photoconductive binder material with marking particles therein dispersed throughout said softenable binder is also disclosed. Imaging is accomplished by providing a migration force across the migration imaging member and developing the member whereby the migration marking material migrates in depth in the softenable layer in imagewise configuration.

Abstract: An imaging system wherein an imaged migration-type imaging member is provided and either the background of image areas of said image are selectively reduced to a more transparent condition. The imaged member comprises a softenable layer containing agglomerable materials in both image and complementary background configurations. Such imaged members may be provided by migration imaging techniques described herein. This member is contacted with solvent vapors capable of softening the softenable layer and heated, thereby causing the agglomerable material to selectively agglomerate in one of either the background or image areas.

Abstract: An imaging member comprising an overlayer of material preferably photosensitive, on a softenable, electrostatically deformable layer is imaged by frost or relief wrinkling the deformable layer. In a preferred mode, where the overlayer is photosensitive, wrinkling is caused by uniformly electrostatically charging the member, exposing said member to an imagewise pattern of radiation actinic to said overlayer of photosensitive material and softening the softenable, electrostatically deformable layer to cause it to wrinkle thereby effecting the overlayer in a variety of ways to produce a variety of imaged members.

Abstract: A migration imaging electrical latent image erasing process comprising providing an imaging member comprising fracturable migration material in a softenable layer; said member having a first electrical latent image of a first polarity, erasing said first electrical latent image by electrically charging said member with charge of a polarity opposite said first polarity to bring said member in imaging area portions to at least about zero potential, then forming a later electrical latent image, typically differing in composition from said first electrical latent image, which may be of either polarity, on said member. If said member is migration developed, migration material migrates at least in depth in said softenable layer in an image configuration corresponding to said later electrical latent image and not said first electrical latent image.

Abstract: Graphic reproductions are achieved by the image-wise modification of the triboelectric charging capability of a surface followed by the triboelectric charging of the modified surface to produce a charge pattern corresponding to an image. The charge pattern may be developed with finely divided colored electroscopic particles and the resulting colored image either fixed on the surface of the insulating member or transferred to a receiving surface and fixed thereon.
