ABSTRACT:
A drive system for rotation of a photosensitive member carried in a removably mountable housing of a process kit used in an image-forming apparatus. The drive system includes a rotatable helical gear loosely carried on a shaft secured to the rotatable photosensitive member. The loosely mounted helical gear is longitudinally movable along the shaft of the photosensitive member and serves to limit any longitudinal movement of the photosensitive drum and thus the process kit housing relative to the image-forming apparatus.
