Claim Text:
1. A developing cartridge comprising: a developing roller extending in an extending direction, the developing roller being rotatable about a first axis extending in the extending direction; a cartridge frame defining an internal space for accommodating a developing agent therein, the cartridge frame having a first side wall and a second side wall separated from the first side wall in the extending direction; a coupling rotatable about a second axis extending in the extending direction, the coupling being positioned at an opposite side of the first side wall from the internal space, the coupling including a first gear rotatable with the coupling, the first gear being rotatable about the second axis; a second gear positioned at an opposite side of the second side wall from the internal space; a first cover covering at least a portion of the first gear, the first cover having an inside surface facing the first side wall and an outside surface being opposite to the inside surface of the first cover in the extending direction, and the first cover having a first engagement portion positioned at the outside surface of the first cover between the first axis of the developing roller and the second axis of the coupling when projected in the extending direction; and a second cover covering at least a portion of the second gear, the second cover having an inside surface facing the second side wall and an outside surface being opposite to the inside surface of the second cover in the extending direction and the second cover having a second engagement portion positioned at the outside surface of the second cover between the first axis of the developing roller and the second axis of the coupling when projected in the extending direction, wherein a surface of the coupling is exposed on the outside surface of the first cover.
