Abstract
A spherical silicone additive is selected and introduced into a contact region between a photoreceptor's anti-curl layer and an electrophotographic system's backer bar, and into a bulk material of the electrophotographic system's spots blade. The additive reduces frictional drag and wear at the contact region between the anti-curl layer and the backer bar and at a contact region between a photoreceptor's outermost surface and the system's spots blade. The reduction of photoreceptor drag and wear at the above contact regions reduces photoreceptor surface irregularities, excessive backer bar wear, excessive spots blade wear, belt ripple and belt contamination. As a result, system drive torque requirements may be minimized, the life of the contacting system components may be extended and system performance may be improved.
