Abstract
A cartridge includes a developing roller and a frame configured to support the developing roller. A lever is connected to the frame, with the lever being movable relative to the frame, and with a part of the lever protruding beyond the frame. The cartridge also includes a spring deformable in response to a movement of the lever relative to the frame, with the spring being positioned such that it is capable of exerting a first force on the lever and a second force on the frame. A memory board is provided and an electrode portion is connected to the memory board. A part of the electrode portion and a part of the spring are positioned in a plane that is perpendicular to a rotational axis of the developing roller.
