Abstract
An imaging system using a migration imaging member comprising a softenable photoconductive material with a fracturable layer of migration marking material contacting the softenable photoconductive material and having the fracturable layer spaced apart from at least one surface of the softenable layer and typically contiguous to the free surface of the softenable material. Imaging with a member comprising a softenable photoconductive binder material with marking particles therein dispersed throughout said softenable binder is also disclosed. Imaging is accomplished by providing a migration force across the migration imaging member and developing the member whereby the migration marking material migrates in depth in the softenable layer in imagewise configuration.
Claims25
An imaging method comprising the steps of:
- a. providing an imaging member comprising a photoconductive softenable material layer containing migration marking particles;
- b. electrically charging said member;
- c. exposing said member to an image pattern of activating radiation and;
- d. developing an image by decreasing the resistance of the photoconductive softenable material to migration of migration marking particles through the photoconductive softenable material whereby selected portions of the migration marking particles imagewise migrate in depth in the softenable layer.
An imaging method comprising:
- providing an imaging member comprising a photoconductive softenable layer comprising photoconductive softenable material, said softenable layer containing a fracturable layer of migration marking material contacting one surface of said softenable layer and said softenable layer being otherwise substantially devoid of migration marking material,
- substantially uniformly electrically charging said imaging member,
- exposing the imaging member to an image pattern of activating radiation, and
- developing an image by decreasing the resistance of the softenable material to migration of migration marking material through the softenable material whereby selective portions of the migration marking material imagewise migrate in depth in the softenable layer.
