CARTRIDGE AND DRUM UNIT FOR ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE Russian patent published in 2021 - IPC G03G21/18 

FIELD: physics.

SUBSTANCE: present invention relates to a cartridge and a drum unit used for an electrophotographic type device for image forming, such as a laser printer. Disclosed cartridge comprises: a frame, a rotatable carrying member intended for transfer of developer, a rotating element resting on said frame with possibility of rotation, connecting element made with possibility of rotation around its rotation axis and including the first part made with through hole, and the second part more distant from the specified rotating element, than the specified first part, wherein said connecting member is movable between a first position in which the axis of rotation of said connecting member is coaxial with respect to the rotation axis of said rotating member, and a second position, in which said connection element rotation axis is inclined relative to rotation axis of said rotating element, and rod-like part passing through said through hole so that said connecting element can be inclined relative to rod-shaped part, and having opposite end parts resting on said rotating member; and a rotating force receiving portion configured to contact said through hole and receive a rotary force from the connecting member, wherein the first angle of maximum inclination, to which said connecting member can be inclined in a first imaginary plane, comprising an axis of rotation of said rotating member and axis of said rod-shaped part is less than second angle of maximum inclination, on which said connecting element can be inclined in second imaginary plane perpendicular to first imaginary plane.

EFFECT: technical result consists in the realization of the purpose, as well as in the elimination of the shortcomings of the analogues of the prior generation of equipment.
