Abstract: The invention discloses a process cartridge detachably installed in an imaging device with a driving head along an installation direction, the process cartridge including: a housing, a driving force receiving member capable of receiving a rotation driving force of the driving head, a rotatable component rotatably supported by the housing and capable of receiving a force of the driving force receiving member to rotate, and a force receiving part arranged on the housing. When the process cartridge is installed in the imaging device and the driving force receiving member generates interference with the driving head in the installation direction, the driving force receiving member is movable and engageable with the driving head as the driving head rotates. The technical problem that the driving force receiving member in the process cartridge cannot be normally disengaged from the driving head in the imaging device in the prior art is solved.

Abstract: Disclosed herein is a process cartridge comprising: a housing; a rotatable component; a driving force receiver configured to transmit a driving force to the rotatable component; an elastic member; wherein when the process cartridge is installed in an imaging device comprising a driving head, the driving force receiver has a first state and a second state relative to the driving head, the first state being a state in which the driving force receiver contacts the driving head and is in a pre-engaged position and the second state being a state in which the driving force receiver is engaged by the driving head; wherein when the driving force receiver is in the first state relative to the driving head, the elastic member is configured to urge the driving force receiver to transition from the first state to the second state as a result of rotation of the driving head.
