In a cartridge, a developing roller (16) is configured to rotate around a first rotational axis extending in a predetermined direction and to carry developer thereon, the developing roller having a first end and a second end apart from each other in the predetermined direction, a from-first-to-second direction being defined along the predetermined direction as being directed from the first end to the second end. A developing electrode (81) is formed of a conductive material and is configured to be electrically connected to the developing roller, the developing electrode including a main part (94) and a protruding portion (88) protruding from the main part in the from-first-to-second direction. A detection body (82) is formed of an insulating material and is rotatably supported by the protruding portion, the detection body including a first opening that exposes part of the protruding portion and a covering portion (95) covering part of the protruding portion. |
