FIELD: photography.
SUBSTANCE: group of inventions relates to cartridges for an electrophotographic imaging apparatus. Substance: the main assembly of the apparatus includes a part for applying a displacement force, an engagement part of the main assembly, driven by an electric engine with a drive shaft, a part for applying a rotating force provided on the drive shaft, and an electrophotographic photosensitive drum. The cartridge is therein detachable from the main assembly without removing the electrophotographic photosensitive drum from the main assembly. The cartridge comprises: a developing roller for developing a latent image formed on the electrophotographic photosensitive drum, rotatable around the axis of the roller; a rotating element for transmitting a rotating force to the developing roller; a coupling element rotatable around the axis of the coupling by means of the rotating force imparted by the engagement part of the main assembly, wherein the coupling element includes a part for receiving the rotating force, engagable with the part for applying a rotating force, to receive the rotating force from the engagement part of the main assembly, and a part for transmitting the rotating force for transmitting the rotating force to the rotary element; a cage including a part for receiving the displacement force, receiving the displacement force from the part for applying a displacement force and supporting the developing roller and the rotary element.
EFFECT: prevented unevenness of rotation of the developing roller, increased imaging speed.
