摘要： Disclosed is an image forming apparatus. The image forming apparatus includes a housing having a discharge port, a plurality of photosensitive bodies mounted in the housing, a transfer unit to transfer visible images formed on the plurality of photosensitive bodies onto a printing medium, a fusing unit to fuse transferred visible images to the printing medium, and a reverse unit to reverse a moving direction of the printing medium, after the printing medium has passed through the fusing unit. As the moving direction of the printed printing medium is reversed by the reverse unit, the printing medium may be discharged while a printed surface of the printing medium is directed downward, allowing a user to easily draw out the printing medium.
