FIELD: image forming devices.
SUBSTANCE: present invention relates to cartridge and electrophotographic image forming apparatus in which cartridge is mounted with possibility of disconnection. Proposed process cartridge for electrophotographic image forming apparatus comprises electrophotographic photosensitive drum, first connecting element, developing roller for latent image development, formed on said electrophotographic photosensitive drum, rotated around its roller axis, and the second coupling element, which rotates around the axis of the second coupling element by means of a rotational force received from the second engaging part of the primary node, wherein said second coupling element includes a second part of adopting a rotating force engaged with the second part of applying a rotating force for adopting a second rotating force, which must be transmitted to said developing roller from the second engaging part of the main assembly, and second transmission part of rotational force for transmitting the second rotational force to said developing roller from said second part of receiving the rotational force, wherein said first coupling element has the possibility of a pivoting movement, so that the side of the axis of the first coupling element, located on the side of the first part of the adoption of the rotational force mentioned, is positioned ahead from the side of the axis of the first coupling element, mounted on side of the first transmission part of rotational force, with respect to removal direction, and said first connecting element is disengaged from the first engaging part of the main assembly by means of a first pivoting movement, and said second connecting element is capable of pivoting movement, so that the side of the axis of the second coupling element located on the side of the second part of the adoption of the rotating force mentioned, is positioned ahead from the side of the axis of the second coupling element, located on the side of the second transmission part of the rotational force, with respect to the direction of removal, and said second coupling element is disengaged from second engaging part of main assembly by means of second pivoting movement.
EFFECT: technical result is to provide a developing cartridge, which can be removably mounted in the main unit of the electrophotographic image forming device by the user, allowing the user to keep the image forming device in good condition (without relying on the service personnel), thereby ensures significant improvement in device electrophotographic imaging with respect to convenience and ease of use, in particular with regard to its content and maintenance.
