Abstract
Abstract A partially migrated migration imaged member comprising a softenable layer and migration marking material partially migrated in image configuration in depth in said softenable layer in response to an electrical latent image of a first polarity is uniformly charged to a low potential opposite the polarity of the electrical latent image of a first polarity, either with or without uniform, e.g., ambient exposure to electromagnetic radiation to thereby desensitize the partially migrated image to further softening development. Charging to low opposite polarity potential during softening development can be used to terminate the effect of development.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
51 words
An imaging process according to claim 1 wherein said partially migrated migration imaged member comprises a softenable layer and migration material partially migrated in image configuration in depth in said softenable layer and a complementary background image configuration of migration material in layer configuration contiguous a surface of said softenable layer.
Claim 2
Dependent Claim
13 words
An imaging process according to claim 2 wherein said migration material is particles.
Claim 3
Dependent Claim
31 words
An imaging process according to claim 3 wherein step (b) is performed while said migration material is being imagewise migrated during softening development, and is carried out to stop said migration.
Claim 4
Dependent Claim
26 words
An imaging process according to claim 3 wherein the potential In step (b) is below the threshold for migration of either image configuration of migration material.
Claim 5
Dependent Claim
26 words
An imaging process according to claim 3 wherein the process is carried out while being exposed to electromagnetic radiation which is activating for said migration material.
Claim 6
Dependent Claim
21 words
An imaging process according to claim 3 including the step of softening said softenable layer either during or after step (b).
