Abstract
Rolls, belts and other biasable members having minimal sensitivity to relative humidity changes are described. Biasable members having at least one layer or coating of a hydrophobic elastomeric polyurethane change little in resistivity when changes in relative humidity occur. The utility of such biasable members is in the transfer of xerographic images from a photoconductor to a final support sheet where the member, for example, a bias transfer roll, electrically cooperates with a photoconductor to establish a directional force field therebetween.
