Claims18
An intermediate transfer member consisting of said member that has transferred thereto a developed xerographic image from a photoconductor and wherein said member consists of a mixture of a carbon black filler, a thermoplastic polyimide and a polybenzimidazole and wherein said thermoplastic polyimide is represented by the following formulas/structures wherein R is phenyl and wherein n is from about 100 to about 1,000
- and an optional release layer.
An intermediate transfer member consisting of a photoconductor containing a developed xerographic image thereon and which image is transferred to said member consisting of a mixture of a conductive filler of carbon black, a thermoplastic polyimide and a polybenzimidazole, wherein said thermoplastic polyimide is selected from the group consisting of those represented by the following formulas/structures wherein R is phenyl and n is from about 100 to about 1,000
- and wherein said polybenzimidazole is represented by the following formulas/structures
- wherein n represents the number of repeating segments of from about 30 to about 500 and wherein said member has a Young's Modulus of from about 3,000 to about 8,500 Mega Pascals, and a coefficient of thermal expansion of from about 15 to about 55 ppm/K.
An abrasion resistant xerographic intermediate transfer member consisting of a mixture of a thermoplastic polyimide, a polybenzimidazole, and an optional carbon black conductive filler, and wherein said member possesses a Young's Modulus of from about 3,500 to about 6,500 Mega Pascals and a coefficient of thermal expansion of from about 25 ppm/K to about 55 ppm/K and wherein said thermoplastic polyimide is represented by
- wherein R is phenyl and n is the number of the repeating units wherein n is a number of from about 100 to about 300 and wherein said polybenzimidazole is represented by the following formulas/structures
- wherein n represents the number of repeating segments of from about 30 to about 500.
