A developing cartridge comprising:
- a casing configured to accommodate developer therein, the casing including one end portion and another end portion separated from the one end portion in a first direction;
- a developing roller rotatable about a first axis extending in the first direction, the developing roller including a developing roller gear, the developing roller having an outer circumferential surface including one end portion and another end portion in a second direction, the one end portion being exposed to an outside of the casing, the another end portion being positioned inside the casing;
- a memory positioned at the one end portion of the casing;
