CARTRIDGE Russian patent published in 2022 - IPC G03G21/18 G03G21/10 

FIRLD: imaging technology.

SUBSTANCE: present invention relates to a cartridge applicable in an electrophotographic imaging device. The cartridge contains a frame containing a camera, a photosensitive drum supported by a frame with the possibility of rotation relative to its axis, while a part of the photosensitive drum is located in the chamber, the first coupling element functionally connected to the photosensitive drum, so that the first coupling element has the ability to transmit rotational force to the photosensitive drum, and the first coupling element includes a protrusion passing outside the cartridge, the second coupling element located next to the hole in the cartridge. In this case, the second coupling element includes a shaft and a protrusion at the end of the second coupling element, while the first coupling element, the second coupling element and the hole are located on one side of the cartridge relative to the axial direction of the photosensitive drum. In this case, the chamber communicates through the fluid with the hole, while the second coupling element forms at least part of the passage through which the toner can move from the chamber to the hole.

EFFECT: simplification of maintenance for various technological means.
