Image forming apparatus having toner replenishment
An apparatus includes a developer container to and from which a replenishment container is attachable and detachable and which includes an accommodating portion and a replenishment port, a transfer portion configured to transfer a developer image on an image bearing member onto a recording material, a supporting tray including a supporting surface configured to support the recording material thereon, and a discharge portion configured to discharge the recording material, onto which the developer image has been transferred, on the supporting surface, wherein the supporting surface has an opening portion opening such that the replenishment port is exposed through the supporting surface, and wherein an opening/closing member configured to be movable between a closed position where the opening/closing member covers the replenishment port and serves as a part of the supporting surface and an open position where the replenishment port is exposed is provided.
1. An image forming apparatus to which a replenishment container accommodating developer is detachably attachable, the image forming apparatus comprising:
an image bearing member configured to rotate while bearing a developer image;
a developer bearing member configured to bear the developer and supply the developer to the image bearing member;
a developer accommodating unit including an accommodating portion configured to accommodate the developer to be borne on the developer bearing member, and a replenishment port to which the replenishment container is detachably attached and through which the developer is supplied from the replenishment container to the accommodating portion;
a transfer portion configured to transfer the developer image on the image bearing member onto a recording material;
a tray including a supporting surface configured to support the recording material from below, the tray having an opening portion, through which the replenishment port is exposed, in the supporting surface;
a discharge portion configured to discharge, in a discharge direction, the recording material onto which the developer image is transferred on the supporting surface of the tray, and
an opening/closing member be movable between an open position where the opening/closing member opens the opening portion of the tray to expose the replenishment port outside the image forming apparatus so that the replenishment container is capable of being attached to the replenishment port, and a closed position where the opening/closing member (1) closes the opening portion of the tray to cover the replenishment port, (2) is in a space, and (3) is configured to support the recording material from below together with the supporting surface of the tray, the space being a space in which the replenishment container attached to the replenishment port is to be when the opening/closing member is in the open position.
2. The image forming apparatus according to claim 1 , wherein the tray is openably and closably supported by an apparatus body in which the image bearing member, the developer accommodating unit, the developer bearing member, and the transfer portion are provided, and
wherein the opening/closing member is openably and closably supported by the tray.
3. The image forming apparatus according to claim 1 , wherein the replenishment port is open upward.
4. The image forming apparatus according to claim 1 , wherein the replenishment port is open upward and downstream in the discharge direction so as to be inclined with respect to a gravity direction.
5. The image forming apparatus according to claim 1 , wherein the opening/closing member is configured not to move from the open position to the closed position in a state where the replenishment container is attached to the replenished port.
6. The image forming apparatus according to claim 1 , wherein the opening/closing member pivots about a pivot axis between the open position and the closed position, and
wherein the pivot axis extends in the discharge direction.
7. An image forming apparatus to which a replenishment container accommodating developer is detachably attachable, the image forming apparatus comprising:
an image bearing member configured to rotate while bearing a developer image;
a developer bearing member configured to bear the developer and supply the developer to the image bearing member;
a developer accommodating unit including an accommodating portion configured to accommodate the developer to be borne on the developer bearing member and a replenishment port to which the replenishment container is detachably attached and through which the developer is supplied from the replenishment container to the accommodating portion;
a transfer portion configured to transfer the developer image on the image bearing member onto a recording material;
a discharge portion configured to discharge, in a discharge direction, the recording material onto which the developer image is transferred, and
a tray configured to move between a first position where the tray exposes the replenishment port outside the image forming apparatus so that the replenishment container is capable of being attached to the replenishment port, and a second position where the tray (1) covers the replenishment port, (2) is in a space, and (3) is configured to support, from below, the recording material discharged by the discharge portion, the space being a space in which the replenishment container attached to the replenishment port is to be when the tray is in the first position.
8. The image forming apparatus according to claim 7 , wherein when viewed in a gravity direction, the replenishment port overlaps with a supporting surface of the tray by which the recording material is supported from below.
9. The image forming apparatus according to claim 7 , wherein the tray has a supporting surface configured to support, from below, an entire region of the recording material discharged by the discharge portion.
10. The image forming apparatus according to claim 7 , wherein the tray is configured to pivot about a pivot axis between the first position and the second position, and
wherein the pivot axis extends in a direction orthogonal to both the discharge direction and a gravity direction.
11. The image forming apparatus according to claim 10 , wherein the pivot axis is positioned upstream of the replenishment port in the discharge direction.
12. The image forming apparatus according to claim 7 , wherein the tray is positioned downstream of the replenishment port in the discharge direction when the tray is in the first position.
13. The image forming apparatus according to claim 7 , wherein the replenishment port is configured so the replenishment container is detachably attached to the replenishment port in a gravity direction when the tray is in the first position.
14. The image forming apparatus according to claim 7 , wherein the replenishment port is open upward.
15. The image forming apparatus according to claim 7 , wherein the replenishment port is open upward and downstream in the discharge direction so as to be inclined with respect to a gravity direction.
