A toner supply container includes a rotatable container body and a sealing member provided at its axial end portion. The sealing member is movable in an axial direction and includes a sealing portion to seal and unseal an opening of the container body when in first and second relative positions, respectively, and a coupling portion positioned to receive a rotational drive force for rotating the sealing member and the container body. The coupling portion includes an elastically displaceable supporting portion, an engaging portion, and a displacing force receiving portion, which are integrally molded. The engaging portion includes a rotational force receiving portion for receiving a rotational drive force for rotating the sealing member and the container body, and a locking portion. The displacing force receiving portion is provided on the supporting portion at a position closer to the container body than the engaging portion.

If a user is not familiar with the operation for the developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. by increasing a rotation load of a second gear 6 which is in an operable connection with a drive gear member 12 of the developer receiving apparatus 10 by a function of a locking member 7, the developer supply container 1 mounted to the developer receiving apparatus 10 is rotated toward the supply position. After the developer supply container 1 rotates to the supply position, the locking by the locking member 7 is released, by which the rotation load applied to the second gear 6 is reduced, so that drive transmission, thereafter, to the feeding member 4 for developer supply is smooth.

In the case that a developer supply container is provided with a feeding portion for feeding a developer by receiving a rotational force and a pump portion for discharging the developer by reciprocation, and the rotational force and a reciprocating force are received from a main assembly side of an image forming apparatus, there is a liability that a driving connection is not properly established between a portion of the developer supply container for receiving the reciprocating force and a portion of the main assembly side for applying the reciprocating force. The developer supply container is provided with a drive converting mechanism for converting the rotational force received from the main assembly side to a force for operating a volume changing type pump.

A developer supply container is mountable to a developer receiving apparatus including a driving gear, and includes a developer discharging opening; a feeding blade for feeding the developer toward the opening when the container is positioned at a developer discharging position; a drive receiving gear engageable with the driving gear for rotating the feeding blade; a regulating projection for regulating a mounting attitude of the container to prevent engagement between the drive receiving and driving gears. Upon mounting the container, the drive receiving gear is revolvable, with manual rotation of the container, about a rotation center of the container to a set position where the drive receiving gear engages with the driving gear; and a load applier for applying a load to the drive receiving gear to rotate the container from the set position to the discharging position by the rotational force received by the drive receiving gear.

A developer supply container detachably mountable to a developer receiving apparatus and settable in a developer receiving apparatus by a setting operation including at least a rotation toward a setting position, includes a containing portion for containing the developer; a rotatable discharging member for discharging the developer out of said containing portion; drive transmitting means, engageable with a driving gear provided in said developer receiving apparatus and rotatable in a direction opposite the setting direction, for transmitting a rotating force from said driving gear to said discharging member.

A toner container detachably mountable to an image forming apparatus, includes a main body for containing toner; a toner discharging portion having an opening; and a coupling member. The coupling member includes a supporting portion and an engaging portion. The engaging portion is configured and positioned to displace in an inward direction with the supporting portion as the engaging portion enters a hollow cylindrical driving member of an assembly of the image forming apparatus, and is also configured and positioned to engage with a slot of the hollow cylindrical driving member when the supporting portion elastically restores in an outward direction. The engaging portion includes a rotational force receiving portion capable of being abutted in a circumferential direction of the hollow cylindrical driving member to receive a rotational drive force from the hollow cylindrical driving member to rotate the main body with the toner discharging portion.

A toner container detachably mountable to an image forming apparatus, includes a main body for containing toner; a sealing portion for sealing the toner discharge opening; locking projections for snap-fitting engagement with holes provided in a cylindrical member of an image forming apparatus, wherein the projections receive from the cylindrical member unsealing forces for unsealing the toner discharge opening by a relative movement between the sealing portion and the toner container, wherein a number of the locking projections is larger than a number of ribs provided between the holes of the cylindrical member.
摘要:
A toner container detachably mountable to an image forming apparatus, includes a container body for containing toner; and a sealing member. The sealing member includes a sealing portion and a coupling portion. The coupling portion includes a supporting portion provided on the sealing portion and an engaging portion provided at a free end of the supporting portion. The engaging portion includes a rotational force receiving portion and a locking portion. The rotational force receiving portion is capable of being abutted in a circumferential direction of a hollow cylindrical driving member of the image forming apparatus. The locking portion is capable of being abutted in an axial direction of the hollow cylindrical driving member to prevent the sealing member from moving in the axial direction of the container body when the container body moves away from the hollow cylindrical driving member.
