Abstract

A cleaning device includes an accommodating container, a collector, and a remover. The accommodating container has an opening and a receiving port. The collector is in contact with a surface of a cleaned body while rotating, to remove matter on the surface of the cleaned body. The remover has a tip end that is in contact with the surface of the cleaned body to remove the matter. The accommodating container accommodates the collector and the remover. The collector and the remover are exposed to the cleaned body through the opening. The accommodating container receives, through the receiving port, the matter removed from the cleaned body. The accommodating container is supported in such a manner that the accommodating container can rotate to a position where the matter collected in the accommodating container do not leak through the opening, so as to be separated from the cleaned body.

Claims (48)

1. A cleaning device comprising:

an accommodating container having an opening and a receiving port;

a collector that is in contact with a surface of a cleaned body while rotating, so as to remove matter to be collected on the surface of the cleaned body;

a closing unit configured to close the receiving port when the accommodating container rotates about a rotation shaft so as to be separated from the cleaned body; and

a remover having a tip end that is in contact with the surface of the cleaned body so as to remove the matter on the surface of the cleaned body, wherein

the accommodating container accommodates the collector, the closing unit, and the remover,

the collector and the remover are exposed to the cleaned body through the opening, and

the accommodating container receives, through the receiving port, the matter removed from the cleaned body by the collector and the remover.

2. The cleaning device according to claim 1 , wherein the collector is configured to move to close the receiving port when the accommodating container rotates about a rotation shaft so as to be separated from the cleaned body.

3. The cleaning device according to claim 2 , wherein an outer diameter of the collector is larger than a width of the receiving port in a direction intersecting a rotational shaft direction of the accommodating container.

4. An image forming apparatus comprising:

the cleaning device according to claim 3 ; and

an image carrier configured to carry a formed toner image, the image carrier being the cleaned body, wherein

the cleaning device removes the matter on the image carrier.

5. An image forming apparatus comprising:

the cleaning device according to claim 2 ; and

an image carrier configured to carry a formed toner image, the image carrier being the cleaned body, wherein

the cleaning device removes the matter on the image carrier.

6. The cleaning device according to claim 1 , wherein the collector is disposed upstream of the remover in a rotation direction of the cleaned body and upward of the remover in a vertical direction.

7. The cleaning device according to claim 1 , wherein the cleaning device is detached from the cleaned body after being separated from the cleaned body.

8. An image forming apparatus comprising:

the cleaning device according to claim 1 ; and

an image carrier configured to carry a formed toner image, the image carrier being the cleaned body, wherein

the cleaning device removes the matter on the image carrier.

9. A cleaning device comprising:

an accommodating container having an opening and a receiving port;

a collector that is in contact with a surface of a cleaned body while rotating, so as to remove matter to be collected on the surface of the cleaned body, the collector being configured to move to close the receiving port when the accommodating container rotates about a rotation shaft so as to be separated from the cleaned body; and

a remover having a tip end that is in contact with the surface of the cleaned body so as to remove the matter on the surface of the cleaned body, wherein

the accommodating container accommodates the collector and the remover,

the collector and the remover are exposed to the cleaned body through the opening, and

the accommodating container receives, through the receiving port, the matter removed from the cleaned body by the collector and the remover.

10. The cleaning device according to claim 9 , further comprising:

a closing unit configured to close the receiving port when the accommodating container rotates about a rotation shaft so as to be separated from the cleaned body.

11. An image forming apparatus comprising:

the cleaning device according to claim 10 ; and

an image carrier configured to carry a formed toner image, the image carrier being the cleaned body, wherein

the cleaning device removes the matter on the image carrier.

12. The cleaning device according to claim 9 , wherein an outer diameter of the collector is larger than a width of the receiving port in a direction intersecting a rotational shaft direction of the accommodating container.

13. An image forming apparatus comprising:

the cleaning device according to claim 12 ; and

an image carrier configured to carry a formed toner image, the image carrier being the cleaned body, wherein

the cleaning device removes the matter on the image carrier.

14. The cleaning device according to claim 9 , wherein the collector is disposed upstream of the remover in a rotation direction of the cleaned body and upward of the remover in a vertical direction.

15. The cleaning device according to claim 9 , wherein the cleaning device is detached from the cleaned body after being separated from the cleaned body.

16. An image forming apparatus comprising:

the cleaning device according to claim 9 ; and

an image carrier configured to carry a formed toner image, the image carrier being the cleaned body, wherein

the cleaning device removes the matter on the image carrier.
