FIELD: physics.
SUBSTANCE: present invention relates to an electrophotographic image forming device (image forming device) and a cartridge installed with possibility of detachment into the main unit of the image forming device. Disclosed group of inventions includes versions of cartridges installed with possibility of detachment into electrophotographic image forming device, besides, the above cartridge contains: i) rotating developer transfer member, ii) a connection element for transmitting a rotary force to said developer transfer member and capable of occupying an initial position, parallel to rotation axis of said developer transfer member and offset relative to it, a first inclined position inclined to said developer transfer member, and a second inclined position inclined in a direction different from first inclined position, iii) a pressing portion for pressing said connecting member to incline the axis of rotation of said connecting member relative to the axis of rotation of said developer transfer member and iv) a movable portion capable of occupying a first movement position to induce said connecting member to occupy a first inclined position and a second movement position to induce said connecting member to occupy a second inclined position.
EFFECT: technical result consists in improvement of previous level of equipment and in providing cartridge, installed with possibility of detachment into main unit of electrographic image forming device, in which developer-carrying element is able to come into contact with light-sensitive element and separate from it, as well as cartridge, in which connecting element is able to engage with drive shaft of main unit, when the cartridge is installed in the main assembly and when the developer transfer member moves from the lead position to the developing position, and a cartridge, in which the connecting element is able to disengage from the main assembly drive shaft, when the cartridge is disconnected from the main assembly and when the developer transfer member moves from the developing position to the lead position.
