1. A cartridge comprising:
a developing roller rotatable about a first axis extending in a first direction;
a housing configured to accommodate developer therein, the housing having one end portion and another end portion separated from the one end portion in the first direction;
a coupling rotatable about a second axis extending in the first direction, the coupling being positioned at the one end portion of the housing;
an electrode electrically connected to a component of the cartridge, the electrode being positioned at the another end portion of the housing; and
a detection protrusion positioned at the another end portion of the housing, the detection protrusion being movable according to rotation of the coupling, the detection protrusion being positioned farther from the developing roller than a part of the electrode in a second direction.
