A sheet conveyance apparatus includes a controller controlling a driver to cause a guide to start rotation in a state in which a trailing end in a sheet conveyance direction of a preceding sheet conveyed by a roller pair having a first roller and a second roller such that the trailing end of the preceding sheet is moved from the position above a first guide to a position between a second guide and a sheet support by the rotation of the guide and that a succeeding sheet conveyed by the roller pair subsequently to the preceding sheet passes the position above the first guide after the rotation of the guide. The first roller is rotated by a driving force supplied from a driving source, and the guide rotates about a rotation axis of the first roller while rotating relatively to the first roller.
