Abstract

A round surface metering blade for use in oil release assisted fusing systems of electrophotographic printing and copying machines is disclosed. Conventional metering blades employ flat shim stock made of steel or plastic to dispense and spread release agent oil lubricant uniformly on the fuser roll. An improved metering blade is realized by using a blade having a smooth and rounded roll contact edge. Advantages of the round surface metering blade include: reduced blade wear; increased latitude for blade-roll contact angle; higher reliability; and easier to manufacture with wider dimensional tolerances.
