A self-lubricating cleaner blade for electrophotographic printing and copying applications is disclosed. The self-lubricating cleaner blade provides lubricant necessary to assemble a blade into a cleaner housing and to initiate blade cleaning of a photoreceptor. The lubricant is an integral component of the blade material composition. The cleaner blade is compounded from an elastomer such as polyurethane or silicone rubber, %ton@, a solid lubricant such as Unilin@ a hydroxypolyethylene available from Petrolite, Kynar* or a metal stearate. A blade cleaner containing one of the above-mentioned lubricating compounds provides essentially an ablatable blade which continuously meters lubricant onto a photoreceptor as it wears down in normal cleaning processes. Incorporation of semi-solid or powdered lubricants into the blade material composition enables a reduction or elimination of the need for lubricant materials to be incorporated in a toner or developer composition.
