Claims6
An intermediate transfer member consisting of a supporting substrate of a polyimide, a polyamideimide, a polyetherimide, or mixtures thereof, and a layer of a mixture of a conductive filler component, a polysiloxane, and a biaryl polycarbonate, and wherein said biaryl polycarbonate is represented by the following formulas/structures wherein m is about 20 mole percent, and n is about 80 mole percent and wherein said biaryl polycarbonate has a number average molecular weight of from about 5,000 to about 100,000, and a weight average molecular weight of from about 8,000 to about 300,000
- and wherein said member accepts a xerographic developed image and wherein said member possesses a Young's Modulus of from about 2,500 to about 5,000 Mega Pascals, and a break strength of from about 70 to about 150 Mega Pascals, and wherein said polysiloxane is polydimethylsiloxane, the conductive filler is carbon black and the ratio of carbon black, biaryl carbonate/polydimethylsiloxane is 12.8/87/0.2.
An intermediate transfer member consisting of a mixture of a biaryl polycarbonate, a polysiloxane, and a conductive filler component, and wherein said member possesses a Young's Modulus of 3,800 Mega Pascals and a break strength Modulus of 120 Mega Pascals, and which mixture is readily releasable from a metal substrate, and wherein said biaryl polycarbonate is represented by the following formulas/structures wherein m is 20 mole percent and n is 80 mole percent, and wherein said biaryl polycarbonate has a number average molecular weight of from about 5,000 to about 100,000, and a weight average molecular weight of from about 8,000 to about 300,000.
- and wherein said member accepts a xerographic toner developed image and wherein said biaryl polycarbonate possesses a glass transition temperature of from about 180° C. to about 300° C.
