Abstract
A fuser oil supply roller including an oil impregnated rubber roller and an outer metering layer of known fluid transfer characteristics for an electrophotographic printer fuser. The roller allows silicone oil to be secreted from the metering layer onto a fuser hot roller to prevent toner from adhering to the fuser hot roller, as well as serving to provide a smooth toner surface. Such a roller provides oil to the fuser hot roller without the need for a separate oil reservoir and delivery system. Therefore, a precisely metered supply of oil is provided to the fuser hot roller while reducing complexity and moving parts. A buffer layer is also provided for minimizing the roller volume given to the oil impregnated rubber roller. A barrier layer may be employed to prevent oil migration into the buffer layer. Furthermore, methods for applying a toner repelling substance to a fuser roller are provided.
