PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE DRUM UNIT Russian patent published in 2020 - IPC G03G21/18 

FIELD: image forming devices.

SUBSTANCE: present invention relates to a process cartridge, an electrophotographic image forming apparatus, and an electrophotographic photosensitive drum unit. Disclosed process cartridge, installed with possibility of removal into main assembly of electrophotographic image forming device, including drive shaft, having rotary force, by moving in direction of installation, substantially perpendicular to axis of said drive shaft, wherein said process cartridge comprises: i) light-sensitive drum rotating about drum axis, ii) a connecting member provided in the axial end portion of said photosensitive drum and rotated around the axis of the connecting member so as to transmit driving force from the drive shaft to the light-sensitive drum, wherein said connecting element is adapted to tilt relative to said photosensitive drum, so that axis of connecting element is inclined relative to drum axis, and iii) a control portion surrounding said connecting member to limit the inclination range of said connecting member, wherein said adjustment part is provided with a recess which is recessed in the installation direction away from said drum axis, and angle between connecting element axis and drum axis is larger, when at least part of said connecting element is in said recess, which is recessed in installation direction away from said drum axis, than, when said connecting element contacts the other part of said control part.

EFFECT: technical result consists in increasing the operability of the maintenance of the image forming apparatus by enabling the user to efficiently perform the maintenance operation of the device, as well as providing electrophotographic photosensitive drum rotation accuracy.
