1. An image forming apparatus comprising:

an image forming apparatus main body;

a plurality of developer image forming parts provided in the image forming apparatus main body that form a developer image; and

a discharged developer recovery container that recovers developer discharged from at least two of the plurality of developer image forming parts,

each of the plurality of developer image forming parts having an image forming structure having only one image holder that holds the developer image, and

the image forming structure in the at least one developer image forming part and the discharged developer recovery container being attached/removed, integrally with each other, in/from the image forming apparatus main body.

2. The image forming apparatus according to claim 1 , wherein the image holder of the image forming structure attached/removed in/from the image forming apparatus main body integrally with the discharged developer recovery container holds a black developer image.

3. The image forming apparatus according to claim 1 ,

wherein the plurality of developer image forming parts respectively have a developing device that develops a latent image, and

the discharged developer recovery container recovers the developer discharged from at least two of the developing devices.

4. The image forming apparatus according to claim 3 , wherein the image forming structure has a removed developer recovery part that recovers developer removed from the image holder.

5. The image forming apparatus according to claim 1 , wherein an opening used for recovery of the developer is formed on an upper end side of the discharged developer recovery container.

6. The image forming apparatus according to claim 5 , wherein the discharged developer recovery container has an opening/closing part to open/close the opening.

7. The image forming apparatus according to claim 6 , wherein the opening/closing part sets the opening into an opened state in accordance with an operation to attach the discharged developer recovery container in the image forming apparatus main body, and sets the opening into a closed state in accordance with an operation to remove the discharged developer recovery container from the image forming apparatus main body.

8. The image forming apparatus according to claim 1 , wherein the discharged developer recovery container has a conveyance member that conveys recovered developer in the discharged developer recovery container.

9. The image forming apparatus according to claim 1 , wherein the discharged developer recovery container is attachable/removable in/from the image forming structure.

10. The image forming apparatus according to claim 1 , wherein the plurality of developer image forming parts are arranged in different positions in the direction of gravity.

11.
