    • PROBLEM TO BE SOLVED: To provide a process cartridge and a developing cartridge capable of stably transmitting a drive force from an image forming device to a developing roller or the like while satisfying a demand that the developing cartridge should be reduced in size. SOLUTION: An input gear 40 is supported not only by an input gear shaft 49 provided in a developing casing 30 but also by a gear cover 47 (protrusion 100) provided from a side opposite to the developing casing 30 relative to the input gear. By this, even though the input gear 40 is reduced in size, the input gear shaft 49 supporting the input gear which is also reduced in size in accordance with the size-reduced input gear 40 can stably support the input gear 40 in cooperation with the protrusion 100 of the gear cover 47.
