Abstract
An image fixing apparatus includes a fixing roller contactable to an unfixed image, and a back-up roller cooperable with the fixing roller to fix the unfixed image, wherein the back-up roller contains a fluorine surface active agent having an antistatic effect substantially to reduce electrostatic offset and enable the back-up roller to remove toner deposited on the fixing roller.
