A sheet reversing mechanism for an image forming apparatus including a switchback reverse path for reversing print sheets, including a transfer roller, a drive motor, and a driving force transmission mechanism. The transfer roller transfers a print sheet along the switchback reverse path. The drive motor rotates in a forward direction and in a reverse direction. The driving force transmission mechanism transmits driving force generated by rotation of the drive motor to the transfer roller. The driving force transmission mechanism includes a clutch configured to connect or disconnect transmission of the driving force to the transfer roller.
