FIELD: image forming devices.
SUBSTANCE: claimed invention relates to a technological cartridge and an electrophotographic image forming device, into which a process cartridge is removably mounted. Disclosed process cartridge, installed with possibility of extraction in main assembly of electrophotographic image forming device, which includes rotary force applying part, wherein the process cartridge comprises a photosensitive drum, a rotating flange member provided at one end in the longitudinal direction of said photosensitive drum and rotated together with said photosensitive drum, a first frame unit supporting said photosensitive drum, a connecting member configured to receive a rotary force for rotating said photosensitive drum from said rotary force portion, in a state where said process cartridge is mounted in said main assembly, wherein said connecting member is connected to said flange member so as to be inclined relative to axis of said photosensitive drum, a first positionable portion on the side of the cartridge, engaged with the first positioning portion on the side of the main assembly provided in said main assembly to limit movement of said first frame unit in the longitudinal direction of said photosensitive drum, in a state where said process cartridge is mounted in said main assembly, a first limiting portion provided on said first frame unit to limit movement of said photosensitive drum in longitudinal direction, and a first confined portion provided on said flange member and in contact with said first limiting portion to limit movement of said photosensitive drum in a longitudinal direction, note also that chamfered part is provided on end section of said first limiting part relative to direction of rotary motion of said photosensitive drum.
EFFECT: technical result consists in the exact positioning of the connecting element of the process cartridge, which is intended for perception of the rotating force from the main assembly of the electrophotographic image forming device, relative to the main assembly of the device transmitting the rotating force, wherein positioning takes place along axial line transmitting rotational force part, as well as in possibility of accurate alignment of axial line of electrophotographic photosensitive element with axial line of interacting part of main assembly of electrophotographic image forming device, and also in the possibility of accurately alignment of the axial line of the connecting member with the axial line of the interacting part of the main assembly of the electrophotographic image forming device.
