The cleaning portion of a cleaning blade made of an elastomeric material is coated with graphite fluoride by applying graphite fluoride powder directly to the blade or applying to the blade a dispersion of graphite fluoride powder in a solvent and evaporating the solvent. Alternatively, graphite fluoride powder can be mixed with the elastomeric material from which the cleaning portion of the cleaning blade is formed.
