  • Process cartridge and electrophotographic image forming apparatus
    Patent number: 10768573
    Abstract: A process cartridge and an electrophotographic image forming apparatus. The process cartridge includes a cartridge body, a photosensitive drum having a first axis, and a driving force receiving member having a second axis. The photosensitive drum is rotatably supported between two end walls of the cartridge body, and the driving force receiving member has a head portion and a shaft portion. The driving force receiving member is connected to an axial end of the photosensitive drum through an Oldham coupling; a rotation angle limiting mechanism is disposed between the driving force receiving member and the photosensitive drum; and the driving force receiving member is movable in a direction perpendicular to the first axis and rotatable around the second axis such that the second axis is either co-axial or parallel with the first axis.

  • Rotational force driving assembly process cartridge
    Patent number: 9740163
    Abstract: The present invention relates to a rotational force driving assembly and a process cartridge used for being engaged with a rotational force driving head inside an electrophotographic image forming device. The rotational force driving assembly can comprise a hub, a rotational force receiving component, a side plate, and an axis offset adjusting mechanism. When the axis offset adjusting mechanism is not subjected to external force, the axis offset adjusting mechanism enables the axis of the rotational force receiving component to be parallel and offset to the axis of the hub. When the axis offset adjusting mechanism is subjected to external force, the rotational force receiving component extends out to be engaged with the rotational force driving head.
