Abstract

See full text

An image forming apparatus has an image forming station, a mounting portion, and a fixing portion that includes a first rotatable member, a second rotatable member, a rubbing rotatable member configured to rub a surface of the first rotatable member during a rubbing treatment, and a storing portion capable of storing number information. A number of recording materials fed to the fixing portion is counted, written into the storing portion, and used to determine whether to execute the rubbing treatment. In a case in which, in sequence, the recording material is fed to the mounted fixing portion, the mounted fixing portion is removed and replaced with another fixing portion, and the removed fixing portion is remounted, both number information acquired from the storing portion and the number of recording materials fed to the remounted fixing portion are used to determine whether to execute the rubbing treatment.
