Abstract
An image forming apparatus includes a printing unit and a shutter arm unit. The shutter arm unit includes a shutter arm that swings to first and second positions, and a stopper arm, connected to the shutter arm, which protrudes toward a transportation path when the shutter arm swings to the second position in which the stopper arm prevents extra sheets of recording media from moving along the transportation path. The force of the paper moving along the transportation path swings the shutter arm unit into the second position, a protrusion cam and an escape cam prevent an increase in the return load of the shutter arm, and a pair of ends of the shutter arm aligns the front end of the sheet of paper.
