Abstract
A developing cartridge includes: a developing roller rotatable about a first axis extending in a first direction; a developing roller gear rotatable together with the developing roller; a coupling gear rotatable about a second axis extending in the first direction; and a joint rotatable together with the coupling gear. The coupling gear is meshingly engaging with the developing roller gear. The joint is pivotally movable relative to the coupling gear about a third axis extending in a second direction. The joint includes: a first protrusion extending in a first radial direction; and a second protrusion extending in a second radial direction opposite to the first radial direction. The second protrusion is positioned away from and is aligned with the first protrusion in a diametrical direction including the first radial direction and the second radial direction. The second direction crosses the first radial direction and the second radial direction.
