Abstract

A toner supply system having: a receiving section that is set in a body of an image forming apparatus so as not to rotate; and a substantially cylindrical toner container that is mountable in and dismountable from the receiving section and that can be driven to rotate on an axis while being mounted in the receiving section, wherein: the toner container has a first toner feeder for feeding toner stored therein toward the receiving section while the toner container is rotated; and the receiving section has a supply port that permits toner fed thereto with rotation of the toner container to drop down and a toner stirrer that extends to a position close to the first toner feeder located inside the toner container while the toner container is mounted in the receiving section.

Claims (21)

1. A toner supply system, comprising:

a receiving section that is set in a body of an image forming apparatus so as not to rotate; and

a substantially cylindrical toner container that is mountable in and dismountable from the receiving section and that can be driven to rotate on an axis while being mounted in the receiving section, wherein:

the toner container has a first toner feeder for feeding toner stored therein toward the receiving section while the toner container is rotated;

the receiving section has a supply port that permits the toner, fed thereto with rotation of the toner container, to drop down and a toner stirrer that extends to a position close to the first toner feeder located inside the toner container while the toner container is mounted in the receiving section; and

one end of the toner stirrer is fixed to the receiving section which does not rotate.

2. The toner supply system according to claim 1 , wherein the first toner feeder is a spiral convex or fin formed on an inner wall of the toner container.

3. The toner supply system according to claim 1 , wherein the first toner feeder rotates along with rotation of the toner container.

4. The toner supply system according to claim 1 , wherein the toner stirrer is provided with an auxiliary stirrer having flexibility.

5. The toner supply system according to claim 4 , wherein the auxiliary stirrer is divided into a. plurality of parts.

6. The toner supply system according to claim 4 , wherein, the auxiliary stirrer is arranged on the opposite side to the supply port with respect to a rotational axis of the toner container.

7. The toner supply system according to claim 1 , further comprising: a second toner feeder, which is located between the first toner feeder and the receiving section, for feeding the toner stored in the toner container toward the supply port while the toner container is rotated.

8. The toner supply system according to claim 7 , wherein: the toner stirrer is provided with at auxiliary stirrer having flexibility; and the auxiliary stirrer rubs its tip against the second toner feeder.

9. A combination of a toner receiving section and a substantially cylindrical toner container that is mountable in and dismoutable from the receiving section set in a body of an image forming apparatus so as not to rotate and that can be driven to rotate on an axis while being mounted in the receiving section, the combination comprising:

a first toner feeder for feeding toner stored in the toner container toward the receiving section while the toner container is rotated,

wherein one end of the first toner feeder is located in a position close to a toner stirrer provided in the receiving section: and

one end of the toner stirrer is fixed to the receiving section which does not rotate.

10. The combination according to claim 9 , wherein the first toner feeder is a spiral convex or fin formed on an inner wall of a container body.

11. The combination according to claim 9 , wherein the first toner feeder rotates along with rotation of the container body.

12. The combination according to claim 9 , comprising:

a second toner feeder , which is located between the first toner feeder and a supply port made in the receiving section to permit toner to drop down, for feeding the toner stored in the toner container toward the supply port while the toner container is rotated.
