摘要:
A fuser unit for an image forming apparatus including: a tape-like cleaning member that abuts on a fuser roller and cleans its peripheral surface; a press roller that presses the fuser roller via the cleaning member; a feed roller that feeds said cleaning member; a wind roller that winds the cleaning member therearound; and a controller that actuates a fixing function before an image formation, stops it after said image formation, and rotates and stops the wind roller and/or the feed roller to control a winding quantity of the cleaning member, wherein said controller calculates a toner image amount based on the prescribed number of pages by tracking from a page on which an image is formed just before the image formation is completed, and determines whether or not said cleaning member is wound around the wind roller during a non-fixing period based on the calculated toner image amount.
