ABSTRACT OF THE DISCLOSURE A device for neutralizing static electric charge on a surface comprising a support means, a plurality of resilient, flexible thin fibers having an electrical resistivity of from about 2 x 103 ohm-cm to about 1 x 106 ohm-cm., the fibers being supported by the support means in such manner that the fibers are oriented and extend in a uniform direction, in a brush like configuration from the support means so that the distal ends of the fibers may extend toward a surface which has a static charge which one wishes to neutralize. Preferably, the resilient fibers have a resistivity of from about 4 x 104 ohm-cm.to about 4 x 105 ohm-cm., and are arranged in a linear array of spaced discrete bundles of fibers in a conductive potting composition in the support holder. Preferably the fibers are made of a partially carbonized polyacrylonitrile fiber and the device may be used in an electrostatographic reproducing machine having at least one dicortron charging device.
