The image forming apparatus includes an elastic roller for forming a nip portion for binding and conveying a recording material, the elastic roller including a elastic layer and a parting surface layer, wherein an area which is not passed by the recording material in the nip portion includes an exposed area where a elastic layer of the elastic roller is exposed, and wherein the exposed area includes a portion where a diameter of the exposed area is equal to or less than a maximum diameter of an area of the parting surface layer. The image forming apparatus prevents a rotary body or a pressuring body from contaminating their surfaces for a long time.
