FIELD: printing devices.
SUBSTANCE: invention relates to the field of printing devices and their components. A cartridge for use with the main assembly of an electrophotographic image forming device is proposed. The main assembly includes a drive shaft having a part of the rotational force application. The cartridge is dismountable from the main assembly in a direction substantially perpendicular to the axial direction of the drive shaft. The cartridge includes: i) a developing roller that is rotatable around its axis; and ii) a connecting element engaged with a part of the rotational force application to receive the rotational force for the rotation of the developing roller. The connecting element is able to take the angular position of the transmission of the rotational force for the transmission of the rotational force for the rotation of the developing roller and the angular position in which the connecting element is inclined from the angular position of the transmission of the rotational force. When the cartridge is dismounted from the main assembly, the connecting element moves from the angular position of the transmission of the rotational force to the angular position of the release.
EFFECT: providing a cartridge that can be mounted in a dismounting way in the main assembly of the electrophotographic image forming device by the user, allowing the user to maintain the image forming device in operability (without relying on maintenance personnel), thereby providing a significant improvement in the electrophotographic image forming device in terms of convenience and ease of use, in particular with regard to its maintenance and operational service.
