Abstract:
1. An image forming apparatus comprising: a printing unit which prints an image on paper; an exit member to push the paper out of the image forming apparatus; an exit path which connects an exit of the printing unit to an exit member which pushes the paper outside of the printing unit; a plurality of guide members arranged widthwise of the paper, each guide member having a first guide side to guide the paper coming out of the printing unit along the exit path, wherein when the first guide side is contacted by the paper coming out of the printing unit, each of the plurality of guide members rotate in a first direction and balance themselves with a force applied by the paper, and returns to an original position by rotating in a second direction opposite to the first direction after the paper completely passes through the printing unit; and a reverse path which branches out of the exit path between the exit of the printing unit and the exit member, so that the direction of the movement of the paper, which moves backward along the exit path, is reversed and again supplied into the printing unit when the exit member rotates in a reverse direction, wherein each guide member further comprises a second guide side which guides the paper, which goes backward along the exit path, along the reverse path.
