1. A cartridge comprising:
a housing configured to accommodate developer therein;
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 bearing through which the developing roller shaft is inserted, the supply roller shaft being inserted through the bearing, the bearing being positioned at an outer surface of the housing in the first direction; and
a developing electrode electrically connected to the developing roller shaft, the developing electrode made of conductive resin, the developing electrode being farther away from the outer surface than the bearing in the first direction, the developing electrode including:
a protrusion extending in the first direction, the protrusion being spaced at a distance from the developing roller shaft in a second direction,
wherein the developing electrode is not electrically connected to the supply roller shaft.
