ABSTRACT:
A donor roll for transporting marking particles to an electrostatic latent image recorded on a surface is provided. The donor roll is adaptable for use with an electric field to assist in transporting the marking particles. The donor roll includes a rotatably mounted body. A portion of the body is electrically conductive. The donor roll also includes a dielectric layer mounted on a portion of the electrically conductive portion of the body. The donor roll also includes a first electrode member mounted on the body, adjacent the dielectric layer, and spaced from the electrically conductive portion of the body so that when the electric field is applied to the first electrode member a portion of the field will be transferred to the dielectric layer.
