Abstract
The invention relates to a low tacky, conductive, soft urethane roller for use in a printer. The roller includes a metal salt evenly or homogeneously distributed in a copolymer formed of a diisocyanate, a reactive silicone containing an amine group; and a polyol or a polyamine. The roller can also have a volume resistivity of between about 1E5 ohm-cm and about 5E10 ohm-cm, and includes a metal salt solution in a copolymer formed of a diisocyanate, a reactive silicone containing a hydroxyl group and/or an amine group; and a polyol and/or a polyamine.
