ABSTRACT:
A particulate, resilient, electrically conductive member having a low thermal mass which extends across the width of a conductive backed recording paper and conducts electrical energy to the conductive backing to heat the paper and develop an image.
In a preferred embodiment, a comb-like contact has a plurality of closely spaced resilient fingers which extend across the width of the web and make contact with the conductive backing.
Due to the low thermal mass of the contacting fingers, and the poor thermal path to conduct heat away from the fingers, they rapidly reach the temperature of the paper.
