A developing cartridge comprising: a housing (10, 11) configured to accommodate therein developer; a developing roller rotatable about a first axis extending in a first direction, the developing roller being positioned at one end of the housing in a second direction; a storage medium including an electric contact surface; a resilient member positioned at one end of the housing in the first direction, the resilient member being configured to expand and contract in a third direction crossing the electric contact surface; a first holder (521, 247) positioned at the one end of the housing in the first direction, one end of the resilient member in the third direction being connected to the first holder (521, 247); and a second holder holding the electric contact surface, another end of the resilient member in the third direction being connected to the second holder, the second holder being movable relative to the first holder (521, 247) in the third direction between a first position and a second position closer to the first holder (521, 247) than the first position is to the first holder (521, 247), characterised in that the cartridge is configured such that, in a case where the second holder moves from the first position to the second position, the resilient member expands and pressing force acting in a direction from the second position toward the first position is generated by contraction force of the expanded resilient member, wherein the developing cartridge is configured to be mounted to a frame, the frame including: a guide portion configured to press the second holder in the third direction from the first position toward the second position; and an electric contact configured to contact the electric contact surface, and wherein the cartridge is configured such that the second holder is pressed in the third direction from the first position toward the second position by the guide portion, and is then moved from the second position toward the first position by the pressing force generated by the contraction force of the resilient member to allow the electric contact surface to contact the electric contact after the second holder is moved past the guide portion. a housing (10, 11) configured to accommodate therein developer;
