A developing cartridge includes a housing, a developing roller positioned at one end of the housing in a second direction, a storage medium having an electric contact surface, a resilient member and a first holder positioned at one end of the housing in a first direction, and a second holder holding the electric contact surface. The resilient member can expand and contract in a third direction crossing the electric contact surface. The resilient member has one end connected to the first holder, and another end connected to the second holder. The second holder is movable relative to the first holder in the third direction between a first position and a second position. As the second holder moves from the first position to the second position, the resilient member expands to generate contraction force functioning as pressing force acting in a direction from the second position toward the first position.
