Abstract

A developer container includes: a container body that stores a developer and includes a filling port for the developer; and a container terminal that is attachable to and detachable from the container body. The container body is provided with an identifier that engages with the container terminal and is caused to change own form that can be identified from an outside, by an external force that is applied to detach the container terminal from the container body. The container body is provided with a flow preparation part that separates an inside and outside of the container body before changing the form of the identifier and that allows the air to flow between the inside and outside of the container body after changing the form of the identifier.

Claims (44)

1. A container, comprising:

a container body to store toner and includes a filling port for the toner; and

a container terminal that is attachable to and detachable from the container body and is electrically connectable to a terminal of an image forming apparatus, wherein:

the container is attachable to and detachable from the image forming apparatus and, when attached to the image forming apparatus, is electrically connected to the terminal of the image forming apparatus, and

the container body includes an identifier that engages with the container terminal, the identifier having a physical form which is permanently changed by an external force that is applied to detach the container terminal from the container body.

2. The container according to claim 1 , wherein the identifier includes a protrusion that protrudes from the container body and is to be broken by the external force.

3. The container according to claim 2 , further comprising:

a hole in the container body that is different from the filling port, the hole being disposed at a position that corresponds to a position of the identifier, the hole being blocked by the identifier prior to the identifier having the physical form which is permanently changed.

4. The container according to claim 2 , wherein an inhibition wall that inhibits a hand or a finger from touching the protrusion is disposed around the protrusion.

5. The container according to claim 1 , wherein the identifier is fixed to the container body by thermal caulking.

6. The container according to claim 1 , further comprising:

a discharge port to discharge the toner from the container body; and

a shutter that opens the discharge port in accordance with an attachment operation and closes the discharge port in accordance with a detachment operation.

7. A developing device comprising:

a development housing to store a developer;

a developer carrier to carry the developer in the developer housing and supply the developer to a latent image on a latent image carrier; and

the container to supply the developer which includes the toner to the developer housing according to claim 1 .

8. A processing unit comprising:

a latent image carrier to carry a latent image on a surface of the latent image carrier; and

the developing device according to claim 7 .

9. An image forming apparatus comprising the container according to claim 1 .

10. The container according to claim 1 , wherein the container body includes developer therein which includes the toner.

11. A method of manufacturing a container including: a container body to store toner and includes a filling port for the toner; and a container terminal that is attachable to and detachable from the container body and is electrically connectable to a terminal of an image forming apparatus, the container being attachable to and detachable from the image forming apparatus and, when attached to the image forming apparatus, being electrically connected to the terminal of the image forming apparatus, the method comprising:

permanently changing a physical form of an identifier of the container body which engages with the container terminal with an external force that is applied to detach the container terminal from the container body;

providing the container body with an airflow hole that allows the air to flow between an inside and outside of the container body after the permanent changing of the physical form of the identifier;

sucking residual toner in the container body from the filling port of the container body after the providing; and

filling the container body via the filling port after the sucking.

12. The method according to claim 11 , wherein:

the identifier includes a protrusion that protrudes from the container body, and

the permanent changing includes breaking the protrusion by the external force.

13. The method according to claim 12 wherein:

the container body includes a hole in the container body that is different from the filling port, the hole being disposed at a position that corresponds to a position of the identifier, the hole being blocked by the identifier prior to the identifier having the physical form which is permanently changed and

the permanently changing the physical form of the identifier of the container body causes removal of the identifier from blocking the hole in the container body.

14. The method according to claim 12 , wherein:

an inhibition wall that inhibits a hand or a finger from touching the protrusion is disposed around the protrusion.

15. A container, comprising:

a container body to store toner and includes a filling port for the toner; and

a container terminal that is attachable to and detachable from the container body and is electrically connectable to a terminal of an image forming apparatus, wherein:

the container is attachable to and detachable from the image forming apparatus and, when attached to the image forming apparatus, is electrically connected to the terminal of the image forming apparatus,

the container body includes an identifier that engages with the container terminal, the identifier having a form which is changed by an external force that is applied to detach the container terminal from the container body, and

the container body includes a part that separates an inside and outside of the container body before changing the form of the identifier and allows the air to flow between the inside and outside of the container body after changing the form of the identifier,

wherein the identifier includes a protrusion that protrudes from the container body and is to be broken by the external force.

16. The container according to claim 15 , wherein:

the part separates an inside and outside of the container body before the form of the identifier is changed and allows the air to flow between the inside and outside of the container body after the form of the identifier is changed.
