Abstract
A process cartridge includes a photosensitive drum supported by the frame. A coupling is operatively connected to the photosensitive drum such that a driving force can be transferred from the coupling to the photosensitive drum, and a developing roller is supported by the frame. A first gear is operatively connected to the photosensitive drum and the developing roller such that the driving force can be transmitted from the coupling to the developing roller. A second gear is positioned at a side of the process cartridge, with the second gear having a plurality of teeth, with at least some of the teeth being exposed teeth that are uncovered by the frame and exposed to outside of the process cartridge, and with a tip of at least one of the exposed teeth facing an axis of the photosensitive drum.
