Developer container and image forming apparatus using the same
View Patent ↗A developer container is provided with a container body. An opening is formed through the container body. An opening/closing lid closes the opening. A lid holding frame holds the opening/closing lid in such a manner that the opening/closing lid can move between an open position and a closed position. A stopper stops the opening/closing lid and thereby preventing it from moving toward the open position in a state that the opening/closing lid is located at the closed position. A contact portion comes into contact with a hook portion provided in a container receiving portion when the developer container is inserted into the container receiving portion. A deformable portion deforms the stopper to such an extent that the stopping of the opening/closing lid by the stopper is canceled when the developer container is inserted into the container receiving portion and the contact portion comes into contact with the hook portion.
1. A developer container which contains developer and is to be inserted into and detached from a container receiving portion of an image forming apparatus body, comprising:
a container body that contains developer;
an opening that is formed through the container body;
an opening/closing lid that closes the opening;
a lid holding frame that holds the opening/closing lid in such a manner that the opening/closing lid can move in an opening/closing manipulation direction between an open position where the opening/closing lid exposes the opening and a closed position where the opening/closing lid closes the opening;
a stopper that stops the opening/closing lid to prevent the opening/closing lid from moving toward the open position in a state that the opening/closing lid is located at the closed position;
a contact portion that comes into contact with a hook portion provided in the container receiving portion when the developer container is inserted into the container receiving portion; and
a deformable portion that deforms the stopper to such an extent that the stopping of the opening/closing lid by the stopper is canceled when the developer container is inserted into the container receiving portion and the contact portion comes into contact with the hook portion.
2. The developer container according to claim 1 , wherein:
the stopper and the contact portion are provided in a common deformable portion.
3. The developer container according to claim 1 , wherein:
the deformable portion is a plate piece which is located between cuts formed in the container body and is thereby deformable.
4. The developer container according to claim 1 , wherein:
the stopper and the contact portion are provided separately.
5. The developer container according to claim 1 , wherein:
the stopper is lower than the contact portion; and
the stopper is rendered incapable of contacting the opening/closing lid when the deformable portion is flexibly deformed through the contact of the contact portion and the hook portion.
6. An image forming apparatus comprising:
the developer container according to claim 1 ; and
the image forming apparatus body having the container receiving portion, wherein:
the container receiving portion comprises:
a lid guiding member that guides the opening/closing lid of the developer container as it is moved;
the hook portion that comes into contact with the contact portion and thereby deforms the deformable portion when the developer container is inserted into the container receiving portion;
a lid opening maintaining unit that holds the opening/closing lid after moving the opening/closing lid to the open position by contacting the opening/closing lid in completing insertion of the developer container; and
a lid holding canceling unit that cancels a state that the opening/closing lid is held by the lid opening maintaining unit when the opening/closing lid has reached the closed position in detaching the developer container.
