Imaging process employing electrical or magnetic reverse migration force and softenable materials

A reversal migration imaging process comprising:

• a. providing an imaging member comprising a substrate, a layer of substantially electrically insulating softenable material on said substrate, said softenable material containing a layer of migration material contiguous an interface of said softenable material and said substrate, said softenable material capable of having its resistance to migration of migration material decreased sufficient to allow migration of migration material in said softenable material;
• b. applying a reverse electrical magnetic imagewise migration force to said migration material sufficient to cause imagewise migration of the migration material away from the interface and toward the free surface;
• and
• c. developing said imaging member by decreasing the resistance to migration of migration material in depth in the softenable layer at least sufficient to allow imagewise migration away from said interface of said softenable material and said substrate toward the free surface of the softenable material.
