Abstract
Migration material dispersed throughout a softenable layer is caused to imagewise selectively migrate to at least locations in depth in the softenable layer, by (A) subjecting said migration material to an imagewise migration force and changing the resistance of said softenable layer, to migration of migration material or by (B) subjecting said migration material to a migration force and imagewise changing the resistance of said softenable layer to migration of migration material.
Claims15
An imaging method comprising:
- a. providing an imaging member comprising a layer of softenable material having migration marking material dispersed throughout said softenable material, said softenable material capable of having its resistance to migration of migration marking material decreased sufficiently to allow migration of migration marking material in depth in said softenable material;
- b. applying an electrical latent image to said migration marking material;
- and
- c. developing said imaging member by decreasing the resistance of said softenable layer to migration of migration marking material in depth in the layer of softenable material at least sufficient to allow imagewise migration of migration marking material subject to said migration force at least in depth of said softenable layer.

An imaging method comprising:
- a. providing an imaging member comprising a layer of softenable material having magnitizable migration marking material dispersed throughout said softenable material, said softenable material capable of having its resistance to migration of migration marking material decreased sufficiently to allow migration of migration marking material in depth in said softenable material;
- b. applying an imagewise magnetic field to said migration marking material;
- and
- c. developing said imaging member by decreasing the resistance of said softenable layer to migration of migration marking material in depth in the layer of softenable material at least sufficient to allow imagewise migration of migration marking material subject to said imagewise magnetic field at least in depth in said softenable layer.
