Developer transporting device and image forming apparatus
View Patent ↗A developer transporting device includes a transporting device body having an inlet, an inlet cover member that opens and closes the inlet, a container having an outlet, an outlet cover member that opens and closes the outlet, a restraining member that restrains an opening movement of the inlet cover member, and a releasing member that is capable of releasing the inlet cover member from the state in which the opening movement is restrained. The restraining member restrains the opening movement of the inlet cover member when the outlet cover member is closed. The releasing member releases the inlet cover member from the state in which the opening movement is restrained when the outlet cover member is open.
1. A developer transporting device comprising:
a transporting device body having an inlet through which developer is supplied to the transporting device body;
an inlet cover member that opens and closes the inlet;
a container having an outlet through which developer contained in the container is discharged, the container being detachably supported by the transporting device body;
an outlet cover member that opens and closes the outlet;
a restraining member that is provided on the transporting device body and that restrains an opening movement of the inlet cover member; and
a releasing member that is provided on the container and that is capable of releasing the inlet cover member from the state in which the opening movement is restrained,
wherein the restraining member restrains the opening movement of the inlet cover member when the outlet cover member is closed, and
the releasing member releases the inlet cover member from the state in which the opening movement is restrained when the outlet cover member is open.
2. The developer transporting device according to claim 1 ,
wherein the releasing member includes a projecting portion that projects from the container,
the outlet cover member is moved away from the projecting portion when the outlet cover member is moved to open the outlet,
the restraining member has a gap that allows the projecting portion to pass therethrough and a contacting portion, and
the projecting portion passes through the gap and comes into contact with the contacting portion so that the first cover member is released from the state in which the opening movement is restrained.
3. The developer transporting device according to claim 2 ,
wherein the projecting portion is disposed along a direction in which the container is inserted, and
the gap in the restraining member extends along the direction in which the container is inserted.
4. The developer transporting device according to claim 2 , wherein the restraining member includes a protrusion that protrudes from the contacting portion, and
the protrusion comes into contact with an adjacent member that is disposed adjacent to the protrusion and restrains a posture of the restraining member when the releasing member releases the inlet cover member from the state in which the opening movement is restrained by the restraining member.
5. The developer transporting device according to claim 3 ,
wherein the restraining member includes a protrusion that protrudes from the contacting portion, and
the protrusion comes into contact with an adjacent member that is disposed adjacent to the protrusion and restrains a posture of the restraining member when the releasing member releases the inlet cover member from the state in which the opening movement is restrained by the restraining member.
6. The developer transporting device according to claim 1 , wherein the outlet cover member is moved in a direction substantially orthogonal to a direction in which the container is inserted.
7. The developer transporting device according to claim 2 , wherein the outlet cover member is moved in a direction substantially orthogonal to a direction in which the container is inserted.
8. The developer transporting device according to claim 3 , wherein the outlet cover member is moved in a direction substantially orthogonal to a direction in which the container is inserted.
9. The developer transporting device according to claim 4 , wherein the outlet cover member is moved in a direction substantially orthogonal to a direction in which the container is inserted.
10. The developer transporting device according to claim 5 , wherein the outlet cover member is moved in a direction substantially orthogonal to a direction in which the container is inserted.
11. An image forming apparatus comprising:
an image carrier that rotates;
a developing device that forms a visible image by developing a latent image formed on a surface of the image carrier;
a transfer device that transfers the visible image from the surface of the image carrier to a medium;
a fixing device that fixes the visible image that has been transferred onto the medium; and
the developer transporting device according to claim 1 , the developer transporting device transporting the developer to the developing device.
12. The developer transporting device according to claim 1 , further comprising an inner cover that covers the outlet of the container and opens the outlet when moved in a direction in which the container is inserted,
wherein the outlet cover member covers the inner cover.
13. The developer transporting device according to claim 1 , wherein the releasing member is disposed outside guide members that guide movement of the inlet cover member.
14. The developer transporting device according to claim 1 , wherein the releasing member is provided on the container distant from the outlet cover member.
