Abstract
An image forming apparatus includes an image bearing member; recording material carrying member for carrying a recording material, wherein the recording material carried on the recording material carrying member is urged to the image bearing member while an image on the image bearing member is transferred, in a transfer station, onto the recording material carried on the recording material carrying member; a rotary fixing member which is coated with a parting agent, and is contacted with an unfixed image on the recording material; and a backup member for forming a nip in conjunction with the rotary fixing member, wherein the recording material is conveyed through the nip to fix the image onto the recording material; wherein after fixing the image on the first surface of the recording material, the apparatus is capable of forming the image on the second surface, which is the opposite surface to the first surface and a separating device for separating the image bearing member and the recording material carrying member after the image is transferred onto the second surface of the recording material.
