Abstract
A developing cartridge includes: a cartridge body for accommodating developers; a driving part at a first end in a first direction; a developing roller rotatable about a rotation axis extending along the first direction and positioned at a third end in a second direction; a storage medium for storing information; an electrical contact surface electrically connected to the storage medium and fixed relative to the cartridge body, and a lifting element configured to lift up the cartridge body in the third direction. The electrical contact surface is positioned at the first end in the first direction and is farther away from the developing roller relative to the driving part. The lifting element is farther away from the developing roller in the second direction away from the driving part.
