1. A cartridge comprising:
a developing roller rotatable about a rotational axis thereof;
a frame configured to support the developing roller;
a lever connected to the frame, the lever being elastically deformable such that a first part of the lever is movable relative to a second part of the lever and relative to the frame, and the lever protruding from the frame;
a coupling member configured to transmit a rotational force to the developing roller, the coupling member being rotatable about a rotational axis thereof, and the coupling member being movable relative to the frame in a direction of its rotational axis;
a memory board; and
an electrode portion connected to the memory board,
wherein, when the cartridge is oriented with the lever and the electrode portion at a bottom portion of the cartridge, the lever protrudes downward from the frame, and
wherein, as viewed in a direction of the rotational axis of the developing roller, the coupling member is positioned between the lever and the developing roller.
