ROTATIONAL FORCE DRIVING ASSEMBLY AND PROCESS CARTRIDGE

摘要

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 so as to transmit rotary driving force, comprising a photosensitive member hub, a rotational force receiving component, a side plate, and an axis offset adjusting mechanism of the rotational force receiving component, wherein the axis offset adjusting mechanism can slide relative to the side plate; the axis offset adjusting mechanism of the rotational force receiving component is connected with the rotational force receiving component; when the rotational force driving assembly is not installed into the electrophotographic image forming device, and thus is not subjected to external force, the axis offset adjusting mechanism enables the axis of the rotational force receiving component to make parallel offset relative to the axis of the photosensitive member hub; and after the electrophotographic image forming device is arranged in the rotational force driving assembly and is installed in place, the axis offset adjusting mechanism is subjected to the external force to move relative to the side plate, so that the axis of the rotational force receiving component is coincident with the axis of the photosensitive member hub, the rotational force receiving component extends out along the axial direction of the photosensitive member hub to be engaged with the rotational force driving head, and the driving assembly does not interfere with the rotational force driving head.
