ローラ定着装置のオイル供給方法。 A fixing roller with a built-in heat source fixes the toner image onto the transfer paper by holding and transporting the transfer paper on which the toner image has been formed, and oil is applied to the circumferential surface of this fixing roller to prevent offset of the toner image. In the roller fixing device, the roller fixing device includes an oil-coated felt and an oil supply means for supplying the oil by directly dropping the oil from an oil supply nozzle onto the oil-coated felt. a nozzle support means for supporting the oil supply nozzle in a reciprocating manner along the width direction of the fixing roller; and a nozzle drive means for reciprocating the oil supply nozzle within a range that does not deviate from both sides of the oil application felt. An oil supply method for a roller fixing device, comprising:
