Abstract
A developing cartridge includes a developing frame, a developing roller, a first drive force receiving member, and a first end cover. The first drive force receiving member is configured to receive a driving force to drive the rotation of the developing roller. The developing cartridge further includes a conductive assembly and a first voltage control member. The conductive assembly is capable of switching internally between an electrically connected state and an electrically non-connected state, and the conductive assembly is provided with a first electrical connection portion that is elastically deformable. The first voltage control member is rotatably mounted on the first end cover and configured to move in response to movement of the first drive force receiving member, thereby switching the conductive assembly between the electrically connected state and the electrically non-connected state, thereby facilitating the miniaturization of the developing cartridge.
