Abstract
A developing cartridge includes a developing roller rotatable about a first axis extending in an axial direction of the developing roller, a casing having an outer surface positioned at one end of the casing in the axial direction, an electrode electrically connected to the developing roller and positioned at the outer surface, the electrode extending in the axial direction, a gear, a protrusion, and an adapter having an electric conductivity and detachably attachable to the electrode, the adapter being electrically connected to the electrode in a state where the adapter is attached to the electrode. A total length of the electrode and the adapter in the axial direction in the state where the adapter is attached to the electrode is greater than a length in the axial direction of the electrode in a state where the adapter is detached from the electrode.
