Abstract
There is provided a process cartridge that includes a driving assembly engageable with a driving shaft having a recess in an image forming apparatus. The driving assembly includes a coupling member, configured to receive a driving force from the driving shaft and provided with a power receiving portion engageable with the recess of the driving shaft; and a body portion capable of rotating after receiving the driving force transmitted by the power receiving portion. When the driving assembly is mounted in the image forming apparatus, the power receiving portion can urge the axis of the driving shaft to be inclined with respect to the axis of the driving assembly. The coupling member urges the driving shaft to be inclined to implement engagement and disengagement, thus solving the technical problem in the prior art that the driving assembly has complicated molding process, high production costs and unstable transmission of the driving force.
