Toner cartridge and image forming apparatus

1. A toner cartridge comprising:

a container body that contains toner and that has an opening portion provided on an outer face of the container body and a guide piece provided on the outer face;

a first cover that opens and closes the opening portion; and

a second cover that is supported by the guide piece and configured to slide in a direction opposite to an insertion direction such that the leading edge of the second cover moves from a position closer to the container body than the first cover to a position further from the container than the first cover as the container body is inserted into an image forming apparatus.

2. The toner cartridge according to claim 1 , wherein the second cover includes a pressed mechanism that inclines the second cover so that a front end portion of the second cover moves away from the container body by being pressed when the container body is inserted into the image forming apparatus.

3. The toner cartridge according to claim 2 , wherein the pressed mechanism is pressed a given distance that is equal to or greater than a distance between a bottom face of the first cover and a bottom portion of the container body.

4. The toner cartridge according to claim 2 , wherein the second cover is movable between an original position and an inclined position, and

a position of the second cover is moved toward the original position by the guide piece when the container body is pulled out from the image forming apparatus when the second cover is inclined by the pressed mechanism.

5. The toner cartridge according to claim 1 , wherein the first cover includes a first protrusion that is provided on a side portion of the first cover and that protrudes toward an upper side of the container body,

the second cover includes a second protrusion that is provided on an inner side of a side portion of the second cover, and

the second protrusion comes in contact with the first protrusion when the container body is pulled out from the image forming apparatus so that the first cover slides in an insertion direction of the container body.

6. The toner cartridge according to claim 1 , wherein a pressing force of the second cover exerted on the container body is weaker than a pressing force of the first cover exerted on the opening portion.

7. An image forming apparatus comprising:

a toner cartridge that includes:

a container body that contains toner and that has an opening portion provided on an outer face of the container body and a guide piece provided on the outer face;

a first cover that opens and closes the opening portion; and

a second cover that is supported by the guide piece and is configured to slide in a direction opposite to an insertion direction such that the leading edge of the second cover moves from a position closer to the container body than the first cover to a position further from the container than the first cover as the container body is inserted into an image forming apparatus;

a toner cartridge receiving portion that receives the toner cartridge,

wherein the toner cartridge receiving portion includes a pressing mechanism that is configured to press a pressed mechanism.

8. The image forming apparatus according to claim 7 , wherein a front end portion of a first bottom surface of the second cover is formed to be inclined so that an angle between the first bottom surface and a second bottom surface of the toner cartridge receiving portion is reduced when the first bottom surface is inclined as the pressed mechanism is pressed by the pressing mechanism.

9. The image forming apparatus according to claim 7 , wherein the second cover includes a pressed mechanism that inclines the second cover so that a front end portion of the second cover moves away from the container bodyby being pressed when the container body is inserted into the image forming apparatus.

10. The toner cartridge according to claim 9 , wherein the second cover includes a pressed mechanism that inclines the second cover so that a front end portion of the second cover moves away from the container body by being pressed when the container body is inserted into the image forming apparatus.

11. The image forming apparatus according to claim 9 , wherein the second cover is movable between an original position and an inclined position, and

a position of the second cover is moved toward the original position by the guide piece when the container body is pulled out from the image forming apparatus when the second cover is inclined by the pressed mechanism.

12. The image forming apparatus according to claim 7 , wherein the first cover includes a first protrusion that is provided on a side portion of the first cover and that protrudes toward an upper side of the container body,

the second cover includes a second protrusion that is provided on an inner side of a side portion of the second cover, and

the second protrusion comes in contact with the first protrusion when the container body is pulled out from the image forming apparatus so that the first cover slides in an insertion direction of the container body.

13. A toner cartridge comprising:

a container body that contains toner and that has an opening portion provided on an outer face of the container body and a guide piece provided on the outer face;

a first cover that opens and closes the opening portion; and

a second cover that is supported by the guide piece and is configured to slide in a direction opposite to an insertion direction such that the leading edge of the second cover moves from a position closer to the container body than the first cover to a position further from the container than the first cover as the container body is inserted into an image forming apparatus.

14. The image forming apparatus according to claim 9 , wherein the pressed mechanism is pressed a given distance that is equal to or greater than a distance between a bottom face of the first cover and a bottom portion of the container body.

15. The toner cartridge according to claim 14 , wherein the pressed mechanism is pressed a given distance that is equal to or greater than a distance between a bottom face of the first cover and a bottom portion of the container body.

16. The toner cartridge according to claim 14 , wherein the second cover is movable between an original position and an inclined position, and

a position of the second cover is moved toward the original position by the guide piece when the container body is pulled out from the image forming apparatus when the second cover is inclined by the pressed mechanism.

17. An image forming apparatus comprising:

a toner cartridge that includes:

a container body that contains toner and that has an opening portion provided on an outer face of the container body and a guide piece provided on the outer face;

a first cover that opens and closes the opening portion; and

a second cover that is supported by the guide piece and configured to slide in a direction opposite to an insert direction such that the leading edge of the second cover moves from a position closer to the container body than the first cover to a position further from the container than the first cover as the container body is inserted into an image forming apparatus; and

a toner cartridge receiving portion that receives the toner cartridge,

wherein the toner cartridge receiving portion includes a pressing mechanism that is configured to press a pressed mechanism.
