Process cartridge

A process cartridge comprising:

• a housing;
• a rotatable component;
• a driving force receiver configured to transmit a driving force to the rotatable component;
• wherein when the process cartridge is installed in an imaging device comprising a driving head with a pair of power output arms, 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, in the pre-engaged position, at least a portion of the driving force receiver overlaps the power output arms in an axial direction of the driving head;
• wherein the driving force receiver is configured to transition from the first state to the second state as a result of rotation of the driving head.

A process cartridge comprising:

• a housing;
• a rotatable component;
• a driving force receiver configured to transmit a driving force to the rotatable component;
• a spring;
• wherein the driving force receiver comprises a pair of claws;
• wherein when the process cartridge is installed in an imaging device comprising a driving head with a pair of power output arms, 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 at least one of the claws contact the power output arms and is in an upstream position of the power output arms in an installation direction of the process cartridge and a second state being a state in which the claws is engaged by the driving head to receive a rotation driving force;
• wherein when the driving force receiver is in the first state relative to the driving head, the spring 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.
