An image forming apparatus includes a recording-medium stacking portion, a recording-medium ejection portion and a suctioning/exhausting unit. The recording-medium stacking portion is provided in a body portion or an upper portion of the image forming apparatus. The recording-medium stacking portion stacks recording media on which respective images are formed thereon. The recording-medium ejection portion ejects the recording medium in a recording-medium ejection direction to the recording-medium stacking portion. The suctioning/exhausting unit is located with respect to the recording-medium stacking portion in a direction, which is perpendicular to the recording-medium ejection direction and parallel to a surface of the recording medium staked on the recording-medium stacking portion. The suctioning/exhausting unit suctions air emitted from the recording medium, which is ejected from the recording-medium ejection portion onto the recording-medium stacking portion. The suctioning/exhausting unit exhausts the suctioned air through a filter.
