Cleaning device and image forming device
View Patent ↗A cleaning device includes a cleaning member for removing developer attached to a developer attaching member; a rotation carrying member which is rotatably configured to carry the developer that is removed by the cleaning member; a housing member for housing the developer that is removed by the cleaning member and configured as a part of a developer housing part that surrounds the rotation carrying member; and an elastic member arranged to contact a periphery of the rotation carrying member.
1. A cleaning device comprising:
a cleaning member for removing developer attached to a developer attaching member;
a rotation carrying member which is rotatably configured to carry the developer that is removed by the cleaning member;
a housing member for housing the developer that is removed by the cleaning member, and configured as a part of a developer housing part that surrounds the rotation carrying member; and
an elastic member arranged to contact a periphery of the rotation carrying member, wherein
the elastic member contacts the rotation carrying member at an upper part of the rotation carrying member, and
the rotation carrying member is configured to move toward the housing member.
2. The cleaning device of claim 1 , wherein
the rotation carrying member moves toward the housing member due to a friction force generated between the rotation carrying member when rotating and the elastic member.
3. The cleaning device of claim 1 , wherein
the elastic member is fixed in the housing part.
4. The cleaning device of claim 1 , wherein
the elastic member is disposed on an entire length of the housing part in the axial direction of the rotation carrying member, and
contacts the rotation carrying member over an entire length of the rotation carrying member in the axial direction of the rotation carrying member.
5. The cleaning device of claim 1 , wherein
the elastic member comprises a sponge and is disposed in a space between a supporting member that supports the cleaning member and the housing part.
6. The cleaning device of claim 1 , wherein
the elastic member is arranged on an upstream side of the cleaning member in the rotation direction of the rotation carrying member.
7. The cleaning device of claim 1 , wherein
the housing member is configured to house the rotation carrying member.
8. The cleaning device of claim 1 , wherein
the developer attaching member comprises an image carrier.
9. The cleaning device of claim 1 , wherein
the developer attaching member comprises an endless belt.
10. The cleaning device of claim 1 , wherein
the developer is waste developer.
11. The cleaning device of claim 1 , wherein
the developer is recycle developer.
12. The cleaning device of claim 1 , wherein
the rotation carrying member is pressed by the elastic member, and
the rotation carrying member contacts the housing member at a contacting part on an opposite side from a contacting position with the elastic member.
13. The cleaning device of claim 12 , wherein
the rotation carrying member receives in accordance with its rotation
a reaction force Fa at the contacting part, the reaction force Fa being in a leaving direction away from the developer attaching member and
another reaction force Fb at the contacting part, the reaction force Fb being in an approaching direction toward the developer attaching member; and
the reaction force Fa is greater than the reaction force Fb.
14. An image forming device, comprising:
a cleaning member for removing developer attached to a developer attaching member;
a rotation carrying member rotatably configured to carry the developer that is removed by the cleaning member;
a housing member for housing the developer that is removed by the cleaning member, and configured as a part of a developer housing part that surrounds the rotation carrying member; and
an elastic member arranged to contact a periphery of the rotation carrying member, wherein
the elastic member contacts the rotation carrying member at an upper part of the rotation carrying member, and
the rotation carrying member is configured to move toward the housing member.
15. A cleaning device for a developer attaching member of an image forming device, the cleaning device comprising:
a housing including a developer tank for storing waste developer;
a cleaning member located within the housing and configured to remove the developer from the developer attaching member;
a carrying member rotatably configured within the housing to carry the developer removed by the cleaning member to the developer tank; and
an elastic member arranged to contact a periphery of the carrying member, wherein
the elastic member contacts the rotation carrying member at an upper part of the rotation carrying member, and
the carrying member is configured to move toward the housing.
16. The cleaning device of claim 15 , wherein
the housing further comprises a toner carrying structure configured to receive the waste developer from the carrying member and to send the waste developer to the waste developer tank.
17. The cleaning device of claim 15 , wherein
the elastic member comprises a sponge.
18. The cleaning device of claim 15 , further comprising
a film that seals a gap between the developer attaching member and the housing to seal the waste developer in the housing.
