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 gearwhich is in an operable connection with a drive gear memberof the developer receiving apparatusby a function of a locking member, the developer supply containermounted to the developer receiving apparatusis rotated toward the supply position. After the developer supply containerrotates to the supply position, the locking by the locking memberis released, by which the rotation load applied to the second gearis reduced, so that drive transmission, thereafter, to the feeding memberfor developer supply is smooth.

Developer supply container

A developer supply kit detachably mountable to a developer supplying apparatus comprising a developer supply container and a developer accommodated therein, wherein the developer supply container includes, a developer accommodating portion accommodating the developer, a discharge opening for discharging the developer accommodated in the developer accommodating portion, a drive receiving portion to which a driving force is inputted from the developer supplying apparatus, and a pump portion operable so that an internal pressure of the developer accommodating portion alternately and repetitively changes between a pressure lower than a ambient pressure and a pressure higher than the ambient pressure, by the driving force received by the drive receiving portion, wherein the developer accommodated in the developer supply container includes toner containing binder resin material and a coloring material, the developer satisfies,10&#x2264;(mJ)&#x2264;80,0.4&#x2264;(mJ)&#x2264;2.0,

A developer supply container includes a developer accommodating portion for accommodating a developer, a discharge opening for permitting discharging of the developer from the developer accommodating portion, a drive receiving portion for receiving a driving force, and a pump portion capable of being driven by the driving force received by the drive receiving portion to alternate an internal pressure of the developer accommodating portion between a pressure lower than an ambient pressure and a pressure higher than the ambient pressure by increasing and decreasing a volume of the pump portion. A position of the pump portion is set such that the pump portion starts with a stroke in which the volume increases in an initial action of the pump portion.

Developer supply container and developer supplying system

A developer supply container includes a developer accommodating chamber; a discharge opening; a fluid communication path connecting with the discharge opening; a pump portion having a volume changing with reciprocation and actable at least on the discharge opening; a regulating portion configured to regulate flow of the developer into an entrance region of the fluid communication path; a movable portion configured to move the regulating portion toward and away from the entrance of the fluid communication path; an air flow path provided inside the regulating portion to permit fluid communication between the pump portion and the discharge opening; and an elastic member provided between the regulating portion and the chamber adjacent to the entrance of the fluid communication path.

Developer supply container and developer supplying apparatus

A developer container is detachably mountable to a developer replenishing apparatus and includes a cylindrical accommodation member for accommodating a developer and a coupling portion for engaging with a main assembly coupling portion provided on the developer replenishing apparatus by movement in an inserting direction. In addition, a contact portion contacts an urging portion in the developer replenishing apparatus and receives a push-off force from the developer replenishing apparatus in a direction opposite to the inserting direction, and an engaging portion is engageable with an opening and closing portion provided in the developer replenishing apparatus to receive a force from the opening and closing portion in the inserting direction and against the push-off force in a closing operation of the opening and closing portion when the developer container is inserted into the developer replenishing apparatus.

A developer supply container includes a developer accommodating portion for accommodating a developer, a discharge opening for permitting discharging of the developer from the developer accommodating portion, a drive inputting portion for receiving a driving force, and a pump portion. The pump portion is driven by the driving force received by the drive inputting portion to alternate an internal pressure of the developer accommodating portion between a pressure lower than an ambient pressure and a pressure higher than the ambient pressure. In addition, a regulating portion regulates a position of the pump portion at a start of operation of the pump portion so that in an initial operational period of the pump portion, air is taken into the developer accommodating portion through the discharge opening, and a nozzle portion connected to the pump portion and has an opening at an end that is disposed adjacent to the discharge opening.

A developer replenishment container accommodating assembly, in which a developer replenishment container is removably put in a main body of an accommodating apparatus, replenishes a developer while rotating the developer replenishment container and includes a holding portion provided on the main body and configured to hold the developer replenishment container put in the main body of the accommodating apparatus in a replenishment position for replenishing the developer, and an engaging portion configured to engage with the developer replenishment container when it is positioned in the main assembly. In addition, a biasing member is configured to bias the engaging portion in a predetermined direction so that the developer replenishment container rotating while held by the holding portion is pressed against the holding portion by the biased engaging portion.

If a user is not familiar with the operation for a 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 which is in an operable connection with a drive gear member of the developer receiving apparatus by a function of a locking member, the developer supply container mounted to the developer receiving apparatus is rotated toward the supply position. After the developer supply container rotates to the supply position, the locking by the locking member is released, by which the rotation load applied to the second gear is reduced, so that drive transmission, thereafter, to the feeding member for developer supply is smooth.
