A developing cartridge includes an input gear which receives an external driving force; a developing roller which carries developer; a supply roller that is in contact with the developing roller and supplies the developer to the developing roller; a supply roller gear that is meshed with the input gear to drive the supply roller using a driving force transmitted from the input gear; and a developing roller gear that drives the developing roller with a driving force transmitted from the supply roller gear. The cartridge further includes a housing with a partition wall that partitions the housing into a first chamber that accommodates the developer and a second chamber that houses the developing roller and the supply roller, and an input gear shaft that supports the input gear. The input gear shaft and the partition wall overlap each other as viewed from a side of the developing cartridge. |
