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.
