Document Type and Number:
WIPO Patent Application WO/2019/105353
Kind Code:
A1
Abstract:
A process cartridge (1). The process cartridge (1) comprises a drive assembly (3) engageable with a drive shaft (100) having a recess in an image forming apparatus. The drive assembly (3) comprises: a coupling member (5), configured to receive a driving force from the drive shaft (100) and provided with a power receiving portion (11a) engageable with the recess of the drive shaft (100); and a body portion (7) capable of rotating after receiving the driving force transmitted by the power receiving portion (11a). When the drive assembly (3) is mounted in the image forming apparatus, the power receiving portion (11a) can force the axis of the drive shaft (100) to be inclined with respect to the axis of the drive assembly (3). The coupling member (5) forces the drive shaft (100) to be inclined to implement engagement and disengagement, thus solving the technical problem in the prior art that the drive assembly (3) has complicated molding process, high production cost and unstable transmission of the driving force.
