A roller includes a metal core, a cylinder including polyurethane, and a conductive adhesive between the metal core and the cylinder. The polyurethane includes a solid solution of a transition metal halide salt and includes less than 5% of salt by weight. The transition metal halide salt provides the polyurethane with a uniform conductivity and a uniform resistivity of between 10 ohm-cm and 10 ohms-cms.

Electrically conductive and semi-conductive polymers

An electrically conductive or semi-conductive polymeric material including a metal salt dissolved in a polymer. The metal salt is completed with the polymer, which is what provides the material with its conductive properties. The materials have a resistivity of between 10.sup.5 and 10.sup.12 ohms-cm.
