    • Provided is a photosensitive drum driving assembly, a photosensitive drum assembly, a process cartridge, and an image forming apparatus. The driving assembly including a supporting body and an engaging protrusion is connected to a drive shaft having a triangular twisted hole to transfer a rotary driving force from an image forming apparatus. The engaging protrusion twistedly protrudes to be inserted into the twisted hole, and includes three or more line contact portions on its cross-section perpendicular to the protrusion direction. The line contact portions are in line-contact with the surface of the twisted hole, and at least one portion of a surface formed by continuously joining the line-contact portions along the protrusion direction is a twisted contact-surface to receive the rotary driving force transferred by the drive shaft.
    • 提供了感光鼓驱动组件,感光鼓组件,处理盒和图像形成装置。 包括支撑体和接合突起的驱动组件连接到具有三角形扭转孔的驱动轴,以从图像形成装置传递旋转驱动力。 接合突起扭曲地突出以插入扭转孔中,并且在其垂直于突出方向的横截面上包括三个或更多个线接触部分。 线接触部分与扭曲孔的表面线接触,并且通过沿着突出方向连续接合线接触部分而形成的表面的至少一部分是扭转的接触表面,以接收旋转驱动力 由传动轴传递。
