Abstract
An image forming apparatus has an image forming portion, and a fixing portion including a first rotatable member and a second rotatable member that form a nip, and a detecting portion configured to detect a temperature of the first rotatable member. An acquiring portion acquires a rotation time of the first rotatable member, and a notifying portion provides a notification prompting exchange of the first rotatable member on the basis of an accumulated value of the rotation time of the first rotatable member acquired by the acquiring portion, the rotation time being subjected to weighting on the basis of the temperature of the first rotatable member detected by the detecting portion.
