CONTAINER FOR DEVELOPER SUPPLY Russian patent published in 2019 - IPC G03G15/08 

FIELD: physics.

SUBSTANCE: invention relates to container for developer supply installed with possibility of removal to device for refueling of developer. Disclosed developer supply container comprises: developer holding section; outlet opening; a storage portion configured to store a developer to be discharged through said outlet; pump section; and a rotatable member provided opposite said storage portion, wherein said rotatable member includes: i) a first rotatable hollow compartment which separates a portion of space on the view in the direction of the axis of rotation of said rotatable member and having a first inner space, wherein said first rotatable hollow compartment is configured to rotate a rotational axis of said rotatable member, ii) a first peripheral opening provided in a circular portion of said first compartment, wherein said first peripheral opening is in fluid communication with said first inner space, iii) a first lateral hole provided in the side of said first compartment, which is closer to said pump section relative to the direction of the axis of rotation, to provide fluid communication between said pump section and said first inner space, iv) a second hollow compartment which separates a portion of the space on the view in the direction of the rotational axis of the rotary member and having a second inner space, wherein said second hollow compartment is spaced from said first compartment in rotational direction of said rotatable member, said second hollow compartment being configured to rotate rotational axis of said rotatable member, v) second peripheral opening provided in circular section of said second compartment, wherein said second peripheral opening is in fluid communication with said second inner space, vi) a second side hole provided on the side of said second compartment, which is closer to said pump section relative to direction of rotation axis, to provide fluid communication between said pump section and said second inner space, and vii) developer supply portion for supplying developer into space formed between said first compartment and said second compartment, wherein said first peripheral bore and said second peripheral bore are configured to contact said storage area.

EFFECT: technical result consists in providing a developer supplying container with which the accuracy of supplying the developer from the developer supply container to an image forming apparatus is higher, and, therefore, a developer supply container having a more stable release capability in the image forming apparatus.
