An image forming apparatus includes a shaft rotatably supporting a supporting member on a supporting unit to allow switching while maintaining the supporting unit, between a first state in which first and second members contact an intermediary transfer belt in a first image forming mode, and a second state in which the first transfer member contacts the belt and the second transfer member is spaced from the belt, in a second image forming mode. The supporting shaft is disposed in a range which is downstream of a central portion of the first transfer member which is disposed downstreammost with respect to a moving direction of the belt and which is remote from a surface of the belt beyond a plane including the central portion of the first transfer member and parallel with a surface of the belt facing the first transfer member. |
