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. Disclosed group comprises the process cartridges and image forming devices versions. Process cartridge comprises: located on the process cartridge one side guide member, developer, contained in the process cartridge, having the L1 axis photosensitive drum, wherein the photosensitive drum is supported in the process cartridge with possibility of rotation to enable rotation about the L1 axis, having the L1′ axis development roller, wherein the development roller is made with possibility of latent image development, formed by the developer on the photosensitive drum, and at that, the developing roller is supported in the process cartridge with possibility of rotation to enable rotation about the axis L1' and having the L2 axis connecting element, wherein the connecting element comprises (i) functionally connected to the photosensitive drum the first end part and the developing roller, (ii) the second end part including having the inverted portion at least one protrusion, which faces the L2 axis, and (iii) connecting the first end part and second end part connection part, and for at least part of connecting part, maximum distance from the L2 axis, along perpendicular to the L2 axis line, to the connecting part outermost surface is less than distance between the said facing part and the L2 axis, along perpendicular to the L2 axis line, and for at least part of the second end part, maximum distance from the L2 axis to of second end part outermost surface along perpendicular to the L2 axis line increases with increase in the distance along the L2 axis from connecting part, at that, the connecting element and the guide member relative position is variable between (i) the first relative position, in which the said at least one protrusion end point is at the first distance from the guide member end, with measurement in the L1 axis direction, and (ii) the second relative position, in which the said at least one protrusion end point is at the second distance from the guide member end with measurement in the L1 axis direction, wherein the first distance is greater than the second distance.
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.
