wherein only one of the first and the second conveying rollers is driven to have a same rotation direction of one of the first discharging roller and the second discharging roller and the other conveying roller is rotatably driven when the first and second conveying rollers are engaged.
2. The image forming apparatus according to claim 1, wherein the first and second conveying rollers are disposed with the printing medium interposed between the first and second conveying rollers; and
the intermediate conveying unit includes a driving unit to drive at least one of the first and second conveying rollers such that one of the first and second conveying rollers is selectively distanced from the other.
3. The image forming apparatus according to claim 2, wherein the driving unit includes:
a support lever to support at least one of shafts of the first and second conveying rollers and to selectively distance the first and second conveying rollers from each other; and
a solenoid to actuate the support lever.
4. The image forming apparatus according to claim 3, further comprising a control unit to control the driving unit to distance the first conveying roller from the second conveying roller if a first printing medium being conveyed in the duplex printing path overlaps a following second printing medium passed through the fixing unit at a position at which the intermediate conveying unit is disposed.
5. The image forming apparatus according to claim 2, further comprising a control unit to control the driving unit to distance the first conveying roller from the second conveying roller if a first printing medium being conveyed in the duplex printing path overlaps a following second printing medium passed through the fixing unit at a position at which the intermediate conveying unit is disposed.
6. The image forming apparatus according to claim 1, wherein one of the first and second conveying rollers is rotatably moved to be close to and isolated from the other.
7. The image forming apparatus according to claim 1, wherein the first and second conveying rollers are distanced from each other by rotatably moving one of the first and second conveying rollers.
8. The image forming apparatus according to claim 1, wherein the first conveying roller is a driving roller and the second conveying roller is a driven roller which is rotated by relying on the first conveying roller.
9. The image forming apparatus according to claim 1, wherein the first conveying roller is driven to be rotated in the same direction as a driving roller of the discharging roller unit.
10. The image forming apparatus according to claim 1, wherein the first discharging roller and the second discharging roller are a pair of opposing rollers.
11. An image forming apparatus, comprising:
a first discharging roller and a second discharging roller to regularly rotate such that a printing medium passed through a fixing unit is conveyed to a developing unit along a duplex printing path when the first and second discharging rollers rotate reversely, the first and second discharging rollers performing a printing medium discharge operation to discharge the printing medium from the image forming apparatus when the first and second discharging rollers rotate forwardly; and
an intermediate conveying unit interposed between the fixing unit and the first and second discharging rollers at a jointing point of a simplex printing path and the duplex printing path, to selectively hold the printing medium, including a first conveying roller and a second conveying roller, at least one of the first conveying roller and the second conveying roller being urged in a direction closer with respect to the other of the first and the second conveying rollers, and before or when in a duplex printing mode, at least a portion of a first printing medium overlaps at least a portion of a second printing medium therebetween, being moved in a direction far away with respect to the other of the first and the second conveying rollers to prevent a jam of at least one of the first printing medium and the second printing medium,
wherein only one of the first and the second conveying rollers is driven to have a same rotation direction of one of the first discharging roller and the second discharging roller and the other conveying roller is rotatably driven when the first and second conveying rollers are engaged.
12. A method of improving printing efficiency in an image forming apparatus including a fixing unit, first and second discharging rollers and an intermediate conveying unit, between the fixing unit and the first and second discharging rollers at a jointing point of a simplex printing path and a duplex printing path, including a first conveying roller and a second conveying roller, comprising:
