An image forming apparatus includes an image former for forming an unfixed toner image on a recording material, and a fixer for fixing the unfixed toner image on the recording material. The fixer includes a rotatable member for forming a fixing nip for nipping and feeding the recording material, and a cleaner, movable toward and away from the rotatable member, for cleaning the rotatable member. The apparatus is operable in a blankless image formation mode for forming the toner image without a blank at least at one of a leading end and a trailing end of the recording material. The cleaner contacts the rotatable member when a portion of the rotatable member in a blankless range at the leading end or the trailing end of the recording material reaches a position where the portion opposes the cleaner.
