Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 50 words
An imaging method according to claim 1 wherein said migration particles are of an average particle size from about 0.01 to about 2 microns and are dispersed in said softenable layer and wherein said softenable layer is electrically insulating and is between from about one-half to about 16 microns thick.
Claim 2
Dependent Claim 27 words
An imaging method according to claim 1 wherein said softenable material comprises a a material selected from the group consisting of polystyrenes and aliphatic petroleum hydrocarbon resins.
Claim 3
Dependent Claim 31 words
An imaging method according to claim 1 wherein steps (b) and (c) are repeated at least one additional time to transfer an image pattern to at least one additional transfer member.
Claim 4
Dependent Claim 13 words
An imaging method according to claim 1 wherein the transfer member is paper.
Claim 5
Dependent Claim 15 words
An imaging method according to claim 3 wherein the migration particles are metal free x-phthalocyanine.
Claim 6
Dependent Claim 22 words
An imaging method according to claim 6 wherein the transfer member and imaged member are passed between a pair of pressure rollers.
Claim 7
Dependent Claim 15 words
The imaging method of claim 7 wherein at least one of the rollers is heated.
Claim 8
Dependent Claim 13 words
The imaging method of claim 1 wherein the migration particles comprise zinc oxide.
Claim 9
Dependent Claim 131 words
The imaging method of claim 1 wherein the transfer member is opaque and has a tackifiable layer in contact with said free surface of said imaged member. 11 An imaging method according to claim 1 wherein said imaged member is formed by forming an electrical latent image on an imaging member comprising a layer of electrically insulating softenable material and migration particles in said softenable material, said softenable material capable of having its resistance to migration of said migration particles decreased sufficiently to allow migration of said migration material through said softenable material and developing said electrical latent image by decreasing the resistance to migration of said migration particles through said softenable material at least sufficient to allow imagewise migration of migration particles at least in depth in the softenable layer.
Claim 10
Dependent Claim 34 words
The imaging method according to claim 1 wherein the contacting of the transfer member against the surface of the imaged member is a contact pressure from about 50 to 200 pounds per linear inch.
