Abstract: A sheet conveyance apparatus that conveys a sheet along a curved path shorter than the sheet and corrects skew of the sheet, includes: a conveyance roller that sends the sheet into the curved path; a guide that guides the sheet along the curved path; and a gate that is hinders advance of the leading end, generates a moment about a normal of the sheet passing through the leading end, and allows advance of the leading end by being pushed away by the leading end, wherein the guide includes a projection projecting toward a movement space for the sheet on a surface facing the movement space, and the projection abuts a center portion of the sheet in a longitudinal direction and generates a moment about an axis parallel to an advance direction of a portion that has come into contact with the projection.
