wherein first and second toner container mounting portions have at least one toner outflow hole to outflow toner, respectively, and

wherein the at least one toner outflow hole is opened as at least one of the toner container mounting portions is screw-connected to the toner container and the toner outflow hole is closed as at least one of the toner container mounting portions is separated from the toner container.

2. The image forming apparatus as claimed in claim 1 , wherein a color of toner accommodated in the first toner container is different from a color of toner accommodated in the second toner container.

3. The image forming apparatus as claimed in claim 2 , wherein the toner accommodated in the first toner container is a toner of a black color, and the toner accommodated in the second toner is a toner of a highlight color.

4. The image forming apparatus as claimed in claim 1 , wherein the first toner container mounting groove and the second toner container mounting groove are arranged in parallel to be spaced apart from each other.

5. The image forming apparatus as claimed in claim 1 , wherein the containers are bottle-shaped and each of the toner containers is mounted in each of the toner container mounting grooves so that at least a part of the toner container is exposed out of the image forming apparatus main body.

6. The image forming apparatus as claimed in claim 1 , wherein each of the toner container mounting grooves are formed in an upper housing portion of the image forming apparatus main body and extends vertically downward from the upper housing portion.

7. The image forming apparatus as claimed in claim 1 , wherein each of the toner container mounting portions includes:

a vertical extension portion configured to vertically extend from a bottom surface portion toward an upper housing portion of the image forming apparatus main body.

8. The image forming apparatus as claimed in claim 7 , wherein each of the toner containers comprises:

a container body on which at least one toner discharge hole is formed, and

a shutter member mounted on the container body so as to be arranged in a first position to close the toner discharge hole or in a second position to open the toner discharge hole.

9. The image forming apparatus as claimed in claim 8 , wherein the shutter member is slidable between the first position and the second position in the container body.

10. The image forming apparatus as claimed in claim 9 , wherein each of the toner containers further comprises an elastic pressing member configured to elastically press the shutter member in the first direction, and

the bottom surface portion of the toner container mounting portion has a pressing projection configured to press the shutter member in the second direction when the corresponding toner container is mounted.

11. The image forming apparatus as claimed in claim 10 , wherein the shutter member comprises:

a plate-shaped shutter portion configured to close the toner discharge hole when the shutter member is arranged in the first position,

an elastic member support portion formed to project from an upper surface of the shutter portion to support the elastic pressing member, and

a pressed portion formed to project from a lower surface of the shutter portion to be pressed by the pressing projection when the toner container is mounted.

12. The image forming apparatus as claimed in claim 8 , wherein the container body is mounted on the toner container mounting portion to be bidirectionally rotatable in a predetermined angle range, and

an arrangement of the shutter member is shifted from the first position to the second position by a forward rotation of the container body, and is shifted from the second position to the first direction by a reverse rotation of the container body.

13. The image forming apparatus as claimed in claim 12 , wherein at least one toner discharge hole is formed on a bottom surface portion of the container body, and at least one shutter hole, which is arranged corresponding to the at least one toner discharge hole in the second position, is formed on the shutter member.

14. The image forming apparatus as claimed in claim 12 , wherein at least one fixing projection for fixing the shutter member is provided on the toner container mounting portion, and

at least one fixing groove, into which the fixing projection is inserted, is formed on a bottom surface of the shutter member.

15. The image forming apparatus as claimed in claim 14 , wherein the fixing projection is elastically supported upward by an elastic support member provided on the toner container mounting portion.

16. The image forming apparatus as claimed in claim 12 , wherein a screw projection is formed on a bottom surface portion of the container body, and a screw hole that is screw-fastened to the screw projection is formed on the shutter member.

17. The image forming apparatus as claimed in claim 12 , wherein at least one rotary projection is formed on a side surface portion of the container body, and

at least one rotary guide groove that guides rotation of the rotary projection is formed on an inner side surface of the toner container mounting portion.

18. The image forming apparatus as claimed in claim 17 , wherein at least one vertical guide groove is formed on an inner side surface of the vertical extension portion to guide the rotary projection from the upper housing portion to the rotary guide groove when the toner container is mounted.

19. An image forming apparatus comprising:

an image forming apparatus main body; and

first and second toner containers mounted in the image forming apparatus main body,

wherein the first and second toner containers are respectively mounted in first and second toner container mounting grooves that are concavely formed in a housing portion of the image forming apparatus main body and vertically extend with respect to the housing portion, and

wherein a cover member for covering the first and second toner containers is openably mounted in the image forming apparatus main body.

20. An image forming apparatus as claimed in claim 19 , wherein the cover member is formed of a transparent or semi-transparent material.
