FIELD: electrical equipment.
SUBSTANCE: present invention relates to the process cartridge, electrophotographic image forming apparatus, in which a replaceable process cartridge can be installed, and the electrophotographic photosensitive drum assembly. Claimed group contains variants of process cartridges. Wherein the process cartridge comprises: housing, contained in the housing developer, having the L1 axis photosensitive drum, wherein the photosensitive drum is supported in the housing with possibility of rotation about the L1 axis, provided on the photosensitive drum end the drum flange, wherein the drum flange is made with possibility of rotation with photosensitive drum around the L1 axis, and having the L2 axis and having (i) the first end connecting element, at least part of which is located within the drum flange, and (ii) the second end comprising at least one protrusion, wherein the connecting element is movable between (i) the first position, in which the said at least one protrusion end point is at the first distance from the photosensitive drum, with measurement in the L1 axis direction, and (ii) the second position, in which the said at least one protrusion end point is at the second distance from the photosensitive drum, with measurement in the L1 axis direction, wherein the first distance is greater than the second distance, and at that the connecting element includes the first part, the second part and the third part, where the second part is located between the first part and the third part in the L2 axis direction, and for each of the first part, the second part and the third part maximum distance from the L2 axis to the connecting element outermost surface, with measuring along perpendicular to the L2 axis line, makes (i) D1 in the connecting element first part, (ii) D2 in the connecting element second part, and (iii) D3 in the connecting element third part, where distances D1 and D3 are greater than the distance D2.
EFFECT: technical result consists in creating a process cartridge capable of smoothly rotating the photosensitive drum by installing it in the main unit, not equipped with a mechanism for moving the connecting element on the side of the main unit, in the direction of center line thereof, for transferring the rotational force to the photosensitive drum by opening and closing the main unit cover.
