Abstract
A developing cartridge may include a housing configured to hold toner. The cartridge may further include a developing roller including a developing roller shaft, a supply roller including a supply roller shaft, a developing electrode and a supply electrode.

In some examples, the developing electrode and supply electrode may have angled surfaces that extend toward one another.
Claims6
A developer cartridge comprising:
- a housing configured to accommodate developer therein;
- a developing roller rotatable about a first axis extending in an extending direction, the developing roller including a developing roller shaft extending in the extending direction;
- a supply roller rotatable about a second axis extending in the extending direction, the supply roller configured to supply the developer to the developing roller, and the supply roller including a supply roller shaft extending in the extending direction;
- a developing electrode electrically connected to the developing roller shaft, the developing electrode being positioned at an outer surface of the housing, the developing electrode including:
- a developing protrusion protruding in the extending direction, the developing protrusion being spaced apart from the developing roller shaft;
- and
- a supply electrode electrically connected to the supply roller shaft, the supply electrode being positioned at the outer surface, the supply electrode including:
- a supply protrusion protruding in the extending direction, the supply protrusion being spaced apart from the supply roller shaft, and the supply protrusion being farther from the developing roller shaft than the developing protrusion.
