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.
