This disclosure relates to a technique for rendering a rubber roll conductive without adversely changing its mechanical properties, such as conformability. The foregoing is accomplished by coating virtually any type of rubber roll with a suspension of colloidal graphite in alcohol. Dag Dispersion No. 154 (a trademark of Acheson Colloids Company) is an example of a suitable suspension. Thus, a thin conductive film which maintains its integrity without affecting the mechanical properties of the rubber can be provided. Provision for connection with a power supply can be effected by coating the sides of the roll with the suspension down to the metal shaft or core.
