DEVELOPER SUPPLY CONTAINER AND DEVELOPER SUPPLY SYSTEM Russian patent published in 2020 - IPC G03G15/08 

FIELD: image forming devices.

SUBSTANCE: present invention relates to developer supply container mounted in developer receiving device with possibility of dismantling. Disclosed group of inventions includes variants of developer supply containers. At that, developer supply container includes: developer holding part intended for developer holding, part of developer unloading, which is in fluid communication with part of developer holding, wherein the developer discharge part is located near the first end of the developer holding part, and wherein the developer unloading portion has an unloading hole 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 portion is configured to rotate about its axis of rotation relative to the developer discharge part, wherein the developer holding portion is provided with a gear portion provided around said rotation axis, and on each of opposite sides of developer discharge part guide is provided, wherein each guide includes (i) first part rising from lower part of developer supply container, when distance to second end of developer holding part, which is opposite relative to first end of developer holding part, is reduced, and (ii) a second portion extending from the end of the first portion such that a plane perpendicular to said axis of rotation and passing through the second portion extends through the discharge port end when an unloading channel is formed, through which developer is discharged outside developer supply container, wherein plane parallel to said axis of rotation and passing through second parts of tracks, is between said axis of rotation and discharge hole.

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.
