ABSTRACT:
The image forming apparatus includes a rotatable first rotary member, a rotatable second rotary member brought into pressure contact with the first rotary member, and forming a nip part for nipping and conveying a recording material, first recording material detector located at the vicinity of the nip part downstream of the nip part with respect tot he conveying direction of the recording material for detecting the passage of the recording material, a drive unit for rotatively driving the first rotary member, a brake for applying the brakes to the rotation of the first rotary member, and a controller for controlling the brake, and during jam near the first rotary member, the driving of the drive unit is stopped. Thereby, the amount of wrapping during the wrapping jam of the recording material around the fixing rotary member can be made small.
