The first state is provided due to resilient deformation of the urging member in the first position of the second gear. The second state is provided due to a restoring force of the urging member in the second position of the second gear.
(54) DEVELOPING CARTRIDGE
(57) A developing cartridge includes: a casing; a first gear; a second gear; a cover; a link; and an urging member engaging with the second gear and the link. The second gear is rotatable from a first position to a second position in accordance with the first gear when the second gear engages with the first gear. The link is movable together with rotation of the second gear and pivotally movable relative to the second gear. The link has: a first state
