Recovery container

1. A recovery container comprising:

a container body that is removably attached to an attachment target and that is capable of recovering powder;

a projection provided at the container body in a direction intersecting with an attachment direction of the container body and having a slip-off preventing portion that is formed at a portion on a side opposite to an attachment direction side and that is engaged with an engaging part provided at the attachment target;

an operation part that is provided at the container body, that has the projection on a surface on a side opposite to a container body side, and that urges the projection away from the container body; and

a pushing part that is provided at the container body, that is movable from a first position to a second position located farther from the container body than the first position, and that is capable of pushing the operation part to be away from the container body when moving to the second position.

2. The recovery container according to claim 1 ,

wherein the container body includes

a second operation part different from the operation part, and

a lock part that projects from the container body and is inserted into an opening provided in the attachment target by an operation of the second operation part to lock an attached state between the container body and the attachment target, and

wherein the pushing part moves in association with the lock part.

3. The recovery container according to claim 2 , wherein the pushing part and the lock part are formed as an integral part.

4. The recovery container according to claim 3 , wherein, when the operation part is operated toward the container body in a state in which the lock part locks the attached state between the container body and the attachment target, the operation part comes into contact with the lock part.

5. The recovery container according to claim 4 , wherein, in a state in which the lock part is in contact with the operation part, the slip-off preventing portion of the projection is in contact with the engaging part.

6. The recovery container according to claim 1 , wherein the projection has an inclined portion inclined so as to be gradually separated from the container body, in the attachment direction from the slip-off preventing portion.

7. The recovery container according to claim 2 , wherein the projection has an inclined portion inclined so as to be gradually separated from the container body, in the attachment direction from the slip-off preventing portion.

8. The recovery container according to claim 3 , wherein the projection has an inclined portion inclined so as to be gradually separated from the container body, in the attachment direction from the slip-off preventing portion.

9. The recovery container according to claim 4 , wherein the projection has an inclined portion inclined so as to be gradually separated from the container body, in the attachment direction from the slip-off preventing portion.

10. The recovery container according to claim 5 , wherein the projection has an inclined portion inclined so as to be gradually separated from the container body, in the attachment direction from the slip-off preventing portion.

11. The recovery container according to claim 6 ,

wherein the projection includes

a first inclined portion serving as the inclined portion, and

a second inclined portion formed on the attachment direction side of the first inclined portion and inclined so as to gradually approach the container body, in the attachment direction.

12. The recovery container according to claim 7 ,

wherein the projection includes

a first inclined portion serving as the inclined portion, and

a second inclined portion formed on the attachment direction side of the first inclined portion and inclined so as to gradually approach the container body, in the attachment direction.

13. The recovery container according to claim 8 ,

wherein the projection includes

a first inclined portion serving as the inclined portion, and

a second inclined portion formed on the attachment direction side of the first inclined portion and inclined so as to gradually approach the container body, in the attachment direction.

14. The recovery container according to claim 9 ,

wherein the projection includes

a first inclined portion serving as the inclined portion, and

a second inclined portion formed on the attachment direction side of the first inclined portion and inclined so as to gradually approach the container body, in the attachment direction.

15. The recovery container according to claim 10 ,

wherein the projection includes

a first inclined portion serving as the inclined portion, and

a second inclined portion formed on the attachment direction side of the first inclined portion and inclined so as to gradually approach the container body, in the attachment direction.

16. The recovery container according to claim 11 , wherein the projection has a curved portion that is curved in an arc shape and that connects the first inclined portion and the second inclined portion.

17. The recovery container according to claim 12 , wherein the projection has a curved portion that is curved in an arc shape and that connects the first inclined portion and the second inclined portion.

18. The recovery container according to claim 13 , wherein the projection has a curved portion that is curved in an arc shape and that connects the first inclined portion and the second inclined portion.

19. The recovery container according to claim 6 ,

wherein a recovery port is provided in a recovery path of the powder provided in the container body, a powder discharge unit provided at the attachment target being configured to be connected to the recovery port,

wherein the recovery port is provided with an opening/closing member that is urged in the attachment direction to close the recovery port and, in a state in which the recovery container is attached to the attachment target, that is pushed in a direction opposite to the attachment direction by a periphery of the powder discharge unit to open the recovery port, and

wherein, in a state in which the inclined portion of the projection is in contact with an end of the engaging part, a force, which is converted from an urging force of the operation part and which moves the container body in the attachment direction, is greater than a force, which is applied to the container body from the opening/closing member and which urges the opening/closing member.

20. The recovery container according to claim 1 ,

wherein a transport member is provided in a recovery path of the powder provided in the container body, the transport member being configured to rotate about an axis along an extending direction of the recovery path and transport the powder from one side to the other side in the extending direction of the recovery path,

wherein, in an attached state in which the container body is attached to the attachment target, a force transmission part that is connected to a rotary drive part provided at the attachment target and that transmits a rotational force of the rotary drive part as a rotational force of the transport member, an external discharge port through which the powder transported to the other side in the extending direction of the recovery path is discharged outside of the container body, and an external opening/closing member that is urged in the attachment direction and that closes the external discharge port are provided at a lower part of the container body, and

wherein the projection is disposed at an upper part of the container body on the other side in the extending direction of the recovery path.
