Abstract
A cleaning apparatus for a fixing device wherein a movable cleaning web is brought into contact with a member of the fixing device to thereby clean the fixing member. The amount or time of rotation of a take-up shaft for taking up the cleaning web is reduced stepwise depending on the number of sheets of recording paper having been subjected to image recording. The amount or time of rotation of the take-up shaft is effected by using the relationship between the increase in the diameter of the take-up roller and the number of copies made stored previously.
