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

FIELD: physics.

SUBSTANCE: present invention relates to developer supply container mounted in developer receiving device with possibility of dismantling. Disclosed developer supply container comprises: a developer holding portion configured to receive the developer, a developer discharge portion communicating with the developer holding portion, wherein the developer discharge part has an unloading hole which is configured to form at least a portion of the discharge channel through which the developer can be discharged to the outside of the developer supply container, wherein the unloading channel end is located on the lower side of the developer supply container, and the developer holding part is made with possibility of rotation around its rotation axis relative to the developer unloading part, wherein the developer holding part is equipped with the gear part provided around the said rotation axis, and an engaging part provided on each of the opposite sides of the developer discharge part, wherein each engaging portion is provided below the horizontal plane including said rotation axis, and each engaging portion includes (i) a first portion extending from the first end portion to the second end portion, where the second end portion is closer to the gear portion than the first end portion, wherein said first portion is elevated such that second end portion is closer to said horizontal plane than first end portion, and (ii) a second portion extending from the second end portion of the first portion such that a plane perpendicular to said axis of rotation and passing through the second portion, crosses the end of the discharge channel when the unloading channel, through which the developer is unloaded to the outside of the developer supply container, is formed.

EFFECT: technical result consists in providing a developer supply container configured to simplify the connection of the developer receiving portion with the developer supply container by the developer receiving portion offset, as well as in providing such developer supply container so that the developer supply container and the developer receiving device can be properly connected to each other, at the same time providing a reliable connection between the developer supply container and the developer receiving part.
