<P>PROBLEM TO BE SOLVED: To provide a developing cartridge capable of reducing an occupied area of a gear. <P>SOLUTION: A coupling member 31 to which driving force is input from outside is rotatably supported on a first side plate at a left side of a frame 6. A first developing gear 32 and a second developing gear 41 are respectively provided on a left end and a right end of a developing roller. Driving force is transmitted to the first developing gear 32 from the coupling member 31. A supply gear 42 is provided on a right end of a supply roller. Driving force is transmitted to the supply gear 42 from the second developing gear 41. The coupling member 31 and the supply gear 42 are arranged such that when the coupling member 31 and the supply gear 42 are projected in a horizontal direction with respect to a vertical surface, at least parts of the respective projections are overlapped with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
