An image forming apparatus includes an image forming unit, first and second rotary members, a cleaning mechanism, and a separating mechanism. The first and second rotary members cooperatively form a nip portion configured to nip and convey a recording material while heating and fixing a toner image onto the recording material. The cleaning mechanism includes a collecting roller. The cleaning mechanism is configured to clean the first rotary member by bringing a cleaning web into contact with the collecting roller that is in contact with the first rotary member and rotates together with the first rotary member. The separating mechanism is configured to separate the cleaning web from the collecting roller when the collecting roller is separated from the first rotary member.
