Toner container and image forming apparatus using the same
A toner container of the present invention stores powdery toner to be replenished via a toner outlet thereof and includes a container body. A shutter device is positioned in the toner outlet for selectively opening or closing the toner outlet. The shutter device includes an opening/closing member, a resilient member constantly biasing the opening/closing member from the inside toward the outside of the container body, and a support member supporting the resilient member and opening/closing member. The toner container is simple and-easy to mount and dismount from an image forming apparatus while surely preventing the toner from leaking.
1. An apparatus, comprising:
a body;
a holding compartment within the body configured to accommodate a toner container;
a toner receiving device configured to receive toner discharged from the toner container; and
a retainer configured to selectively retain the toner container in the holding compartment.
2. An apparatus according to claim 1 , wherein:
the retainer is movable in a horizontal direction and is configured to mate with the toner container to prevent the toner container from being removed from the holding compartment.
3. An apparatus according to claim 2 , wherein:
the retainer is configured to prevent the toner container from moving upwardly.
4. An apparatus according to claim 2 , wherein:
the retainer is configured to move away from the container when the container is inserted into the holding compartment.
5. An apparatus according to claim 4 , wherein:
the retainer has an angled surface which contacts the container during insertion of the container, the angled surface arranged to urge the retainer away from the container.
6. An apparatus according to claim 5 , wherein:
the retainer is flexibly connected to a container holder.
7. An apparatus according to claim 6 , wherein the container holder is connected to the holding compartment.
8. An apparatus according to claim 7 , wherein the container holder is connected to the holding compartment by a plastic material.
9. An apparatus according to claim 7 , wherein the container holder is connected to the holding compartment by a metal material.
10. An apparatus according to claim 1 , wherein:
the retainer is configured to engage with a flat portion on the toner container.
11. An apparatus according to claim 10 , wherein:
the retainer is configured to engage with the flat portion of the toner container which is located at a top surface of the toner container.
12. An apparatus according to claim 1 , wherein:
the retainer is configured to engage with a recess of the toner container.
13. An apparatus according to claim 1 , wherein:
the retainer is configured to engage with a recess of the toner container which is at a top surface of the toner container.
14. An apparatus according to claim 12 , wherein:
the retainer is configured to prevent the toner container from moving upward when the retainer is engaged with a recess of the toner container.
15. An apparatus according to claim 14 , wherein:
the retainer is configured to engage with a flat portion of the toner container which is located at a top surface of the toner container.
16. A method of using a powder container, comprising:
moving a powder container in a downward direction so that the powder container contacts a portion of an image forming apparatus;
moving a portion of the image forming apparatus in a horizontal direction;
removing powder from the powder container in a downward direction.
17. A method according to claim 16 , wherein:
the moving of the powder container moves the powder container such that a position of an opening of the powder container corresponds to a position of powder receiving port of the image forming apparatus.
18. A method according to claim 16 , wherein the moving of the powder container comprises:
moving the powder container downwardly such that a sponge member on a bottom of the powder container contacts a portion of the image forming apparatus.
19. A method according to claim 16 , further comprising:
moving a shutter of the powder container to open a lower portion of the powder container.
20. A method according to claim 19 , wherein:
the moving the shutter moves the shutter which resists movement due to a force imposed by a spring.
21. A method according to claim 19 , wherein:
the moving of the shutter moves the shutter in a vertical direction.
22. A method according to claim 16 , wherein:
the moving of the portion of the image forming apparatus moves a stop which retains the powder container from moving upwardly.
23. A method according to claim 16 , wherein:
the moving of the powder container moves a nozzle of the image forming apparatus into the powder container.
24. A method according to claim 23 , wherein:
the moving of the nozzle into the powder container causes a piston of the powder container to contact the nozzle and move upwardly.
25. A method according to claim 16 , wherein:
the removing of powder removes powder through a nozzle.
26. A method according to claim 16 , further comprising:
moving a shutter of the powder container to open a lower portion of the powder container.
27. A method according to claim 16 , further comprising:
injecting air into the powder container in order to remove toner from the powder container.
