In a sheet conveyance apparatus, a sponge roller is provided at a joining portion in which a first sheet conveyance path joins a second sheet conveyance path. A leading edge of a sheet or tailing edge of a sheet abuts at the sponge roller when the sheet is conveyed from the first conveyance path to the second conveyance path. In a projection surface in a direction orthogonal to a sheet conveyance direction in the second sheet conveyance path, an outer periphery of the sponge roller and an outer periphery of a conveyance roller, which is positioned in a downstream side, are partially overlapped in the second conveyance path. Further the sponge roller is rotatably arranged. With such a configuration, the noise generated in the joining portion can be reduced, and effect to reduce the noise can be continued.
