ABSTRACT:
Images are formed with imaging members comprising one or more migration layers and a softenable layer which may be a circulation layer. An electrical latent image is created on the member with electrostatic charge having a density sufficient to cause migration of the marking material from the migration layer through the migration layer - softenable layer interface and into the softenable layer. When the migration layer and softenable layer comprise materials sufficiently dissimilar so as to retard or prevent penetration, the softenable layer is a circulation layer, the circulation of which enables penetration of the interface by marking material. In a multiple migration layer member, the migrated marking particles have their relative positions inverted.
