An imaging system includes a belt roller, an endless belt, a steering member, a tilting mechanism, and a link mechanism. The endless belt rotates about the belt roller which extends in a longitudinal direction. The steering member is located inside the endless belt. The tilting mechanism is operably coupled to a center portion of the steering member. The link mechanism is operably coupled to the tilting mechanism and operates the tilting mechanism so that the steering member is tilted in response to a displacement of the endless belt in the longitudinal direction of the belt roller.
