Abstract

A toner-conveying device includes a movable plate. The movable plate is movable between a holding position such as to couple a cap of a toner container to a nozzle when the toner container is supported by a container holder, and a retreating position such as not to hinder loading and unloading of the toner container in the container holder. The movable plate is placed in the holding position by a cam when the nozzle is coupled to the cap, and is released and moved to the retreating position while the toner container is being loaded or unloaded. In this structure, the cap can be properly positioned in the conveyor device while ensuring the rigidity of a bag of the container within a practically preferable range, without reducing the convenience for the operator.

Claims

1. A toner container, comprising:

a toner storing member which contains toner; and

a cap, provided at a lower portion of the toner storing member, the cap including;

a hole through which toner exits the toner container, the hole configured to receive a horizontal nozzle of an image forming apparatus;

grooves in sides of the cap, the grooves being parallel to the hole and configured to receive corresponding protrusions of the image forming apparatus which are inserted into the grooves in a same direction as the nozzle.

2. A toner container according to claim 1, wherein:

the grooves are provided on opposite sides of the cap, with the hole of the cap disposed between the grooves.

3. A toner container according to claim 1, wherein:

the grooves are configured to be horizontal, when the toner storing member is above the cap and the hole is facing a horizontal direction.

4. A toner container according to claim 1, further comprising:

a shutter which opens and closes the hole.

5. A toner container according to claim 1, further comprising:

a path which communicates in a vertical direction the toner from the toner storing member towards the hole of the cap,

wherein the hole of the cap extends in a horizontal direction.

6. A toner container according to claim 1, further comprising:

a weld attaching the toner storing member to the cap.

7. A method of conveying toner, comprising:

installing a toner container in an image forming apparatus using grooves in a cap of the toner container which are parallel to a horizontal hole in the cap and match with protrusions of the image forming apparatus, the protrusions being inserted into the grooves along a same direction as a nozzle of the image forming apparatus;

communicating toner from a storage volume of the toner container through a vertical path in a cap of the toner container;

communicating the toner from the vertical path to the nozzle of the image forming apparatus, the nozzle being inserted into the horizontal hole in the cap.

8. A method according to claim 7, wherein the installing comprises:

installing the toner container in the image forming apparatus using the grooves in the cap which are on opposite sides of the cap, with the horizontal hole of the cap disposed between the grooves.

9. A method according to claim 7, wherein the installing comprises:

installing the toner container in the image forming apparatus using the grooves which are oriented in a horizontal direction.

10. A method according to claim 7, further comprising:

moving a shutter, which blocks the hole, to an open position.

11. A method according to claim 7, wherein the installing comprises:

installing the toner container by lowering the toner container from a position above a position at which toner is communicated.

12. A method according to claim 7, further comprising:

removing the toner container by raising the toner container from a position at which toner is communicated.

13. A toner container, comprising:

a toner storage volume; and

an interface, including;

a hole through which toner exits the toner container, the hole configured to receive a horizontal nozzle of an image forming apparatus;

grooves in sides of the interface, the grooves being parallel to the hole and configured to receive corresponding protrusions of the image forming apparatus which are inserted into the grooves in a same direction as the nozzle.

14. A toner container according to claim 13, further comprising:

a weld attaching the toner storage volume to the interface.

15. A toner container according to claim 13, further comprising:

a shutter disposed in the hole.

16. A toner container according to claim 15, wherein the shutter has a cylindrical shape.

17. A toner container according to claim 13, wherein the grooves are located at symmetrical positions about the hole of the interface.

18. A toner container according to claim 13, further comprising:

a circuit device including memory at a face of the interface which includes the hole.

19. A toner container according to claim 13, wherein at least a part of the toner storage volume comprises a bag.

20. A toner container according to claim 13, further comprising:

a seal at an inside of the hole.

21. A toner container according to claim 13, wherein the grooves comprise a groove at two sides of the interface.

22. A toner container, comprising:

a toner storage volume; and

a valve portion, including;

a valve body including;

a hole through which toner exits the toner container, the hole configured to receive a horizontal nozzle of an image forming apparatus; and

grooves in sides of the valve portion, the grooves being parallel to the hole and configured to receive corresponding protrusions of the image forming apparatus which are inserted into the grooves in a same direction as the nozzle, and

the valve portion including a valve which closes the hole.

23. A toner container according to claim 22, further comprising:

a weld attaching the toner storage volume to the valve portion.

24. A toner container according to claim 22, wherein the valve comprises a cylindrical shutter.

25. A toner container according to claim 22, wherein the grooves are located at symmetrical positions about the hole of the valve portion.

26. A toner container according to claim 22, further comprising:

a circuit device including memory at a face of the valve body which includes the hole.

27. A toner container according to claim 22, wherein at least a part of the toner storage volume comprises a bag.

28. A toner container according to claim 22, further comprising:

a seal at an inside of the hole.

29. A toner container according to claim 22, wherein the grooves comprise a groove at two sides of the valve portion.
