Developer supply apparatus and developer supply container

1. A developer supply apparatus comprising:

a holding member for detachably holding a developer supply container having a developer discharge opening and a sealing member for sealing the developer discharge opening, wherein said holding member rotatably holds the developer supply container;

a manually rotatable member having a rotational axis and being disposed so as to be rotatable about a rotational axis of the developer supply container;

a converting mechanism, provided at a connecting portion between said rotatable member and said holding member, for converting a rotation of said rotatable member to a sliding operation of said holding member, and

a locking member for locking engagement with the sealing member,

wherein the sealing member moves from a closing position to an opening position by the sliding operation, and

wherein the sliding operation includes a sliding movement for locking the sealing member with said locking member and a sliding movement for a relative movement of a main body of the developer supply container and the sealing member locked with said locking member causes the sealing member and said locking member to move away from each other.

2. An apparatus according to claim 1 , wherein the sliding movements are continuously effected by a rotating operation in one rotational direction.

3. An apparatus according to claim 1 , further comprising a driving portion for rotating the developer supply container to discharge the developer through the developer discharge opening after completion of the sliding operation.

4. An apparatus according to claim 1 , wherein the sealing member moves from the opening position to the closing position by a sliding operation for closing the developer discharge opening.

5. An apparatus according to claim 1 , wherein the sliding operation further includes a sliding movement for closing the developer discharge opening by fitting the sealing member locked with said locking member into the developer discharge opening, and a sliding movement for a relative moment between a main body of said developer supply container in which the sealing member is fitted and said locking member causes the sealing member and said locking member to move away from each other.

6. An apparatus according to claim 5 , wherein the sliding movements are continuously effected by a rotating operation in one rotational direction.

7. An apparatus according to claim 6 , further comprising a releasing member actable on the sealing member to release the sealing member from said locking member, and a release converting mechanism, provided at a connecting portion between said rotatable member and said releasing member, for converting a rotation of said rotatable member to a sliding operation of said releasing member.

8. An apparatus according to claim 7 , wherein said release converting mechanism effects the sliding operation of said releasing member to release the sealing member from said locking member after completion of the sliding movement for fitting the sealing member locked with said locking member into the developer discharge opening, by rotation of said rotatable member for the sliding operation for closing the developer discharge opening.

9. An apparatus according to claim 8 , wherein said release converting mechanism includes an engaging portion provided in said rotatable member and a projection, provided in said releasing member, for engagement with said engaging portion, and the rotational movement of said rotatable member is converted into the sliding operation of said releasing member by said projection being driven by said engaging portion.

10. A developer supply apparatus comprising:

a holding member for detachably holding a developer supply container;

a rotatable member rotatably supported on said holding member; and

a converting mechanism, provided at a connecting portion between said rotatable member and said holding member, for converting a rotational movement of said rotatable member to a sliding operation of said holding member,

wherein said rotatable member is rotatable around the developer supply container held on said holding member and is provided on a peripheral surface thereof with a grip portion for receiving a rotating force.

11. An apparatus according to claim 10 , wherein the developer supply container held on said holding member is movable by a sliding operation between a position where the developer supply container is exchangeable and the position where the developer supply is enabled.
