A method for making a developer roll sleeve in which a core substrate roll is spray coated with a conductive composition including a host resin composition and a wear-resistance imparting additive. Preferably, the host resin composition includes a phenolic thermosetting resin and a conductivity additive such as a carbon black, graphite and the like. Further, the wear resistance imparting additive is preferably selected from the group consisting of a polytetrafluoroethylene resin (e.g., Teflon), graphite, ultra-high molecular weight polyethylene having a molecular weight from about 3,000 to about 4,500 grams, molybedenum disulfide, silicone and mixtures thereof. The wear resistance imparting additive is preferably provided in an amount sufficient to obtain a thickness wear rate of less than about 0.00047 percent per printing cycle.
