Claim 1:
2. The image forming apparatus according to claim 1, wherein, in a cross section substantially orthogonal to a rotational axis direction of the outer roller, in a case where (i) a straight line connecting a rotational center of the inner roller and a rotational center of the outer roller is defined as a nip center line, (ii) a straight line being orthogonal to the nip center line and passing through a contact point of the intermediate transfer belt on the nip center line and the outer roller is defined as a nip tangent line, and (iii) a stretching surface of the intermediate transfer belt formed by the inner roller and the plurality of stretching rollers arranged adjacently to the inner roller on an upstream side of the inner roller in a moving direction of the intermediate transfer belt is defined as a pre-nip stretching surface, the nip tangent line is located closer to the inner roller than the pre-nip stretching surface.
