FIELD: physics.
SUBSTANCE: group of inventions includes a process cartridge which is detachably installed in the basic unit of the electrophotographic imaging device, an electrophotographic imaging device in which the process cartridge is detachably installed in the basic unit of the device, as well as an electrophotographic photosensitive drum unit which is detachably installed in the basic unit of the electrophotographic imaging device. The disclosed process cartridge, which is detachably installed in the basic unit of the electrophotographic imaging device, having a drive shaft, has a part which applies a rotary force by moving in a direction essentially perpendicular to the axis of the drive shaft, wherein the cartridge includes: i) an electrophotographic photosensitive drum revolving about an axis; ii) a connecting element engaged with the rotary force applying part for receiving the rotary force intended to rotate the drum, wherein the connecting element is configured to occupy an angular position for transferring the rotary force, an angular position before engagement and an angular position for disengagement, wherein the connecting element is tilted from the axis; and iii) an adjusting part (170) for adjusting the tilt angle of the connecting element such that the downward tilt angle of the connecting element is less than the tilt angle of the connecting element when the connecting element is in the angular position before engagement, wherein when installing the process cartridge in the basic unit, the connecting element moves from the angular position before engagement into the angular position for transferring the rotary force, and when removing the cartridge from the basic unit, the connecting element moves from the angular position for transferring the rotary force to the angular position for disengagement with the drive shaft.
EFFECT: faster maintenance of the imaging device by enabling the user to efficiently carry out maintenance of the device, high accuracy of rotation of the electrophotographic photosensitive drum.
