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 movable relative to the frame, and a part of the lever protruding beyond the frame;
a spring deformable in response to a movement of the lever relative to the frame, the spring being capable of generating a first force that acts on the lever and generating a second force that acts on 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 protruding part of the lever protrudes downward from the frame, and
wherein, as viewed in a rotational axis direction of the developing roller, the coupling member is positioned between the lever and the developing roller.
