A sheet conveyance apparatus includes a first conveyance path, a detection portion, a second conveyance path, a discharge unit, and a controller. The discharge unit is movable in a width direction and is configured to perform a discharge operation of discharging a sheet onto a first discharge portion and a reversing operation of reversing and conveying the sheet to the second conveyance path. The controller is configured to control the discharge unit and to execute a first alignment control when the reversing operation is performed. The first alignment control is a control in which the discharge unit moves the sheet in the width direction based on a position of the sheet detected by the detection portion to align the sheet at a target position.
