Abstract
In a developing cartridge, a drive-force receiving member includes: a first cylindrical part having a gear part transmitting drive force to a developing roller; a second cylindrical part disposed radially inward of the first cylindrical part and in contact with a support part; and a receiving part receiving drive force from outside of the developing cartridge. The receiving part is disposed outward of the first and second cylindrical parts in an axial direction in which a rotational axis extends. The receiving part has an internal space in communication with a gap between the first and second cylindrical parts. The receiving part is disposed to overlap the gap between the first and second cylindrical parts when the receiving part is viewed in the axial direction. The receiving part has an outward end in the axial direction, at least part of the outward end of the receiving part being closed.
