Abstract
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 1012 ohm-cm and 105 ohms-cms.
