PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGING DEVICE AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE DRUM Russian patent published in 2017 - IPC G03G21/18 

FIELD: physics.

SUBSTANCE: invention relates to a process cartridge, an electrophotographic image forming apparatus, and an electrophotographic photosensitive drum. The inventive process cartridge comprises: i) a photosensitive drum rotating around the drum axis; ii) a rotatable developing roller adapted to develop a latent image formed on mentioned photosensitive drum; iii) a connecting element provided at an axial end portion of mentioned photosensitive drum and rotated about an axis of the coupling element for transferring the driving force to mentioned photosensitive drum. Mentioned connecting element is adapted to tilt with respect to mentioned photosensitive drum, such that the axis of the connecting element is inclined relative to the drum axis; And iv) a control portion surrounding mentioned coupling element for limiting the range in which mentioned connecting element is tilted. Mentioned adjusting portion is provided with a portion that is open in a direction away from mentioned drum axis and away from mentioned developing roller and wherein the angle between the axis of the connecting element and the drum axis is large when at least a portion of mentioned connecting member is in mentioned portion that is open than when mentioned connecting element is in contact with another portion of mentioned regulating portion.

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.
