IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF

摘要

Disclosed are an image forming apparatus capable of increasing the speed of successively discharging printed printing media in order to increase the overall printing speed and a control method thereof. The image forming apparatus according to the present invention includes a first discharge roller to feed printed printing medium rearward from a print unit disposed at an inner front portion of a main body; a reverse roller to reverse a moving direction of the printed printing medium fed from the first discharge roller from a rear to a front of the main body; a second discharge roller to discharge the printed printing medium whose moving direction is reversed outside; and an intermediate discharge roller unit which is provided between the first discharge roller and the reverse roller and includes a main roller, and a sub discharge roller and a sub supply roller which are in contact with the main roller. While a preceding printed printing medium fed from the reverse roller is discharged between the main roller and the sub discharge roller, a following printed printing medium fed from the first discharge roller is supplied between the main roller and the sub supply roller. Accordingly, since the interval between the preceding printed printing medium and the following printed printing medium becomes shorter than that of a conventional image forming apparatus, the speed of successively discharging printed printing media increases, so that the overall printing speed increases.
