Abstract

An image forming apparatus includes an apparatus body, a developer container, a data recording medium, a contact terminal, a detector, and control circuitry. The developer container is detachably attached in the apparatus body. The data recording medium is on the developer container. The contact terminal is disposed in the apparatus body and contacts the data recording medium. The detector detects a communication failure between the data recording medium and the apparatus body. The control circuitry executes a control mode to vibrate the data recording medium when the detector detects the communication failure.

First claim

The invention claimed is:

1. An image forming apparatus comprising:
an apparatus body;
a developer container detachably attached in the apparatus body;
a data recording medium on the developer container;
a contact terminal disposed in the apparatus body, the contact terminal configured to contact the data recording medium;
a detector configured to detect a communication failure between the data recording medium and the apparatus body;
control circuitry configured to execute a control mode to vibrate the data recording medium when the detector detects the communication failure; and
wherein the control mode is a control mode to drive the developer container.

2. The image forming apparatus according to claim 1 ,
wherein the detector is configured to detect whether the communication failure occurs when the developer container is attached to the apparatus body.

3. The image forming apparatus according to claim 1 ,
wherein the developer container includes a container body having an inner surface with a spiral projection, the container body being rotatable around a rotation axis of the container body to discharge developer from a discharge port of the container body, and
wherein the control mode is to drive the container body to rotate the container body.

4. The image forming apparatus according to claim 3 ,
wherein the container body has a protruding portion on a part of an outer circumferential surface of the container body.

5. The image forming apparatus according to claim 4 ,
wherein the container body includes a head portion having the discharge port,
wherein the developer container includes a non-rotatable cap covering the head portion of the container body,
wherein the container body is supported by the non-rotatable cap at a position away from the head portion toward a bottom portion of the container body, and
wherein the data recording medium is disposed on an end face of a projecting end of the cap.

6. The image forming apparatus according to claim 3 ,
wherein the data recording medium is disposed in a non-rotatable manner at a position away from the rotation axis of the container body.

7. The image forming apparatus according to claim 1 ,
wherein the developer container includes a developer conveyor rotatable around a rotation axis of the container body inside the developer container, and
wherein the control mode is to drive the developer conveyor to rotate the developer conveyor.

8. The image forming apparatus according to claim 1 ,
wherein the control mode is to drive the developer container to convey the developer inside the developer container toward a discharge port of the container body.

9. The image forming apparatus according to claim 1 , further comprising a storage portion configured to store the developer discharged from the developer container,
wherein the control circuitry is configured to not execute the control mode in response to a detection that the developer stored in the storage portion has reached a specified amount.

10. The image forming apparatus according to claim 1 ,
wherein the control mode is to drive the developer container to convey the developer inside the developer container in a direction away from a discharge port of the container body.

11. The image forming apparatus according to claim 1 ,
wherein the control mode is to drive the developer container to switch a conveyance direction of the developer inside the developer container between a direction toward a discharge port of the container body and a direction away from the discharge port.

12. The image forming apparatus according to claim 11 , further comprising a storage portion configured to store the developer discharged from the developer container,
wherein the control circuitry is configured to execute the control mode to drive the developer container to convey the developer in the direction toward the discharge port when the developer stored in the storage portion has not reached a specified amount, and
wherein the control circuitry is configured to execute the control mode to drive the developer container to convey the developer in the direction away from the discharge port when the developer stored in the storage portion has reached the specified amount.

13. The image forming apparatus according to claim 1 ,
wherein the control circuitry is configured to execute the control mode again when the detector detects the communication failure immediately after the control circuitry executes the control mode for a specified time.

14. The image forming apparatus according to claim 13 ,
wherein the control circuitry is configured to execute the control mode within a specified number of times.
