OIL EXUDING ROLLER FOR AN ELECTROPHOTOGRAPHIC PRINTER |
摘要 |
An oil supply roller for an electrophotographic printer fuser allows silicone oil to exude from the oil supply roller onto the surface of the fuser hot roller in a controlled fashion to prevent toner from adhering to the fuser hot roller, and also serves to provide a smooth toner surface. A metering layer disposed on an outer surface of the roller provides an even, controlled flow of oil to the surface of the roller. Further, a buffer layer may be employed to decrease the overall volume of the oil bearing layer to decrease the effects of swelling in that layer. Therefore, a precisely metered supply of oil is provided to the fuser hot roller while reducing complexity and moving parts. A method for fabricating the fuser hot roller by impregnating silicone rubber with a toner repelling substance and disposing the impregnated rubber about a rotatable drive shaft is also provided. |
