1. A cartridge, comprising:
a housing that has a developer accommodating portion configured to accommodate developer therein and that includes a first side wall and a second side wall, the first side wall and the second side wall being spaced apart from each other in a predetermined direction and opposing each other in the predetermined direction, a from-first-to-second direction being defined along the predetermined direction as being directed from the first side wall to the second side wall; a coupling member configured to receive driving force from outside, the coupling member being disposed at a position opposite to the developer accommodating portion with respect to the first side wall; a detection body for being detected by an external detecting unit, the detection body being disposed at a position opposite to the developer accommodating portion with respect to the second side wall; a rotating member that is configured to rotate around a rotational axis extending in the predetermined direction, at least part of the rotating member being disposed between the first and second side walls; a first driving force transmission member configured to rotate together with the rotating member around the rotational axis, positioned at the same side with the coupling member with respect to the first side wall, and configured to transmit the driving force from the coupling member to the rotating member; and a second driving force transmission member configured to rotate together with the rotating member around the rotational axis, positioned at the same side with the detection body with respect to the second side wall, and configured to transmit the driving force from the rotating member to the detection body; a developing roller that is configured to carry developer thereon; and a developing electrode that is positioned at the same side with the detection body with respect to the second side wall and that is configured to be electrically connected with the developing roller, wherein the developing electrode includes an electric-power receiving protrusion protruding from the developing electrode in a direction away from the second side wall along the predetermined direction, the electric-power receiving protrusion being configured to be supplied with electric power from outside, wherein the detection body is formed of an insulating material and is rotatably supported by the electric-power receiving protrusion, the detection body including:
a first opening that extends in a rotating direction of the detection body and that exposes part of the electric-power receiving protrusion; anda covering portion that is configured to cover part of the electric-power receiving protrusion, and wherein the detection body is configured to move relative to the electric-power receiving protrusion from a first position through a second position to a third position, the first, second, and third positions being different from one another, the detection body located at the first position allowing the electric-power receiving protrusion to be supplied with electric power via the first opening, the detection body located at the second position preventing the electric-power receiving protrusion from being supplied with electric power by the covering portion, and the detection body located at the third position allowing the electric-power receiving protrusion to be supplied with electric power via the first opening. |
