Abstract
The present teachings provide an intermediate transfer member which includes a substrate layer and a surface layer disposed on the substrate layer. The surface layer includes a polyimide polymer having the formula: wherein R is alkyl or aryl and the like and mixtures thereof; and n and m are the mole percent of the repeating unit.
Claims19
An intermediate transfer member comprising:
- a substrate layer;
- and
- a surface layer disposed on the substrate layer comprising a polyimide polymer having the formula:
- wherein R is alkyl or aryl and mixtures thereof;
- n is from about 50 to about 99 mole percent, and said m is from about 50 to about 1 mole percent of said polyimide polymer and a conductive additive comprising carbon black in an amount of from about 1 weight percent to about 60 weight percent of the intermediate transfer member.

An intermediate transfer member comprising:
- a bottom layer comprising a polyimide polymer;
- and
- a surface layer disposed on the bottom layer comprising a polyhedral oligomeric silsesquioxane (POSS) fluoropolyimide polymer having a hexane contact angle of from about 20° to about 45° and a conductive additive comprising carbon black of from about 5 to about 20 weight percent of the surface layer.
A method of manufacturing an intermediate transfer member comprising:
- dissolving a polyimide having a formula
- wherein R is alkyl or aryl and mixtures thereof;
- and n is from about 50 to about 99 mole percent, and said m is from about 50 to about 1 mole percent of said polyimide polymer, in a solvent;
- milling the dissolved polyimide with a conductive additive comprising carbon black to form a dispersion;
- coating the dispersion on a substrate layer to form the intermediate transfer member;
- and
- curing the dispersion.
