Developer supply container and developer supplying apparatus
A developer supply container includes a developer accommodating portion 2 a for accommodating toner, a developer supply opening 5 b for discharging the toner accommodated in the developer accommodating portion 2 a from the developer supply container 1 , a feeding portion 2 b for feeding the toner in the developer accommodating portion 2 a toward the developer supply opening 5 b , a rotatable drive receiving portion 7 a for receiving a rotational force for rotating the feeding portion 2 b , and a holding projection 4 h held by a holding mechanism 304 provided in the developer supply container 1 to determine a position of the developer supply container 1 , wherein the developer supply opening 5 b is disposed between the drive receiving portion 7 a and the holding projection 4 h . By this, a stability of connection between the discharge opening of the developer supply container and the receiving port of the image forming apparatus side is improved.
1. A developer supplying system comprising:
a developer replenishing apparatus; and
a developer supply container detachably mountable to the developer replenishing apparatus,
wherein the developer replenishing apparatus includes:
a mounting device configured and positioned to demountably mount the developer supply container;
a developer receiver configured and positioned to receive developer from the developer supply container;
a driver configured and positioned to apply a driving force to the developer supply container; and
a single toggle configured and positioned to attract the developer supply container toward a mounting position when the developer supply container is being mounted to the developer replenishing apparatus,
wherein the developer supply container includes:
a developer discharging body;
a developer accommodating body configured and positioned to accommodate the developer;
a discharge opening, provided on the developer discharging body, configured and positioned to discharge the developer accommodated in the developer accommodating body from the developer discharging body;
a feeding portion, provided on the developer accommodating body, configured and positioned to feed the developer in the developer accommodating body toward the developer discharging body;
a gear configured and positioned to receive a rotational force from the driver for rotating the feeding portion; and
a projection to be toggled at each of lateral sides of the developer discharging body, the each projection to be toggled being projected in a direction perpendicular to a rotational axis of the feeding portion,
wherein the discharge opening is disposed between the gear and the projection to be toggled with respect to the rotational axis of the feeding portion and
wherein the toggle is rotatable about a horizontal axis that is perpendicular to the rotational axis of the feeding portion to attract both projections to be toggled into the mounting position, with a mounting operation of the developer supply container.
2. A developer supplying system according to claim 1 , wherein the developer supply container further comprises a pump positioned and configured to force the developer out of the developer supply container through the discharge opening.
3. A developer supplying system according to claim 1 , wherein the rotational axis is below the discharge opening in a vertical direction when the developer container is mounted in the developer replenishing apparatus.
