<p>A fixing apparatus of the invention includes a pressure roller 6 and a fixing roller 7 that make press-contact with each other and an oil roller 8 that makes press-contact with either the pressure roller 6 or the fixing roller 7, and passes a recording sheet through a nip area between the pressure roller 6 and the fixing roller 7 to fix toner on the recording sheet. The fixing apparatus also includes: a pressure roller gear 21 and an oil roller gear 22 that transmit a rotation of a shaft of the pressure roller 6 that makes press-contact with the oil roller 8 to a shaft of the oil roller 8; and a one-way clutch 23 that causes the oil roller 8 to idly rotate in a direction of a driven rotation when the oil roller 8 is driven to rotate by pressing against the pressure roller 6.</p> |
