Developing Cartridge Having Electrode

A developer cartridge comprising:

• a developing roller rotatable about a first axis extending in a first direction, the developing roller including a developing roller shaft extending in the first direction;
• a supply roller rotatable about a second axis extending in the first direction, the supply roller including a supply roller shaft extending in the first direction;
• a housing configured to accommodate developer therein, the housing including a first wall and a second wall spaced from the first wall in the first direction;
• a developing electrode electrically connected to the developing roller shaft, the developing electrode being positioned at an outer surface of the first wall;
• and
• a supply electrode electrically connected to the supply roller shaft, the supply electrode being positioned at the outer surface of the first wall, the supply electrode including;
• a supply contact part extending in the first direction;
• an insertion part through which the supply roller shaft is inserted;
• and
• a coupling part coupling the supply contact part and the insertion part;
• wherein the coupling part is positioned between the outer surface of the first wall and at least a portion of the developing electrode in the first direction.
