Biasable transfer compositions and members having extended electrical life

摘要

An electrically conductive or semi-conductive polymeric material which includes a blend of: (i) a bis[oxydiethylenebis(polycaprolactone)yl]sulfoaryldicarboxylate or a bis[oxydiethylenebis(polycaprolactone)yl]sulfonamidosulfonylaryldicarboxylate, and (ii) a complex of a ferric halide and ethylene glycol or an oligoethylene glycol selected from di-, tri-, or tetraethylene glycol, to provide the material with its conductive properties. The material has a resistivity of from about 106 to about 5x1011 ohm cm and can be used in the fabrication of biasable transfer members such as, for example, a biasable transfer roll to transfer electrostatographic toner images from a photoconductor to a final support material such as a sheet of paper wherein the member electrically cooperates with the photoconductor to establish a directional force field therebetween.
