1. A developing cartridge, comprising:
a developing frame internally provided with a developer chamber configured to accommodate developer;
a developing roller rotatably disposed on the developing frame;
a first drive force receiving member configured to receive a driving force for driving rotation of the developing roller;
a first end cover, connected to the developing frame and at least partially covering the first drive force receiving member;
a conductive assembly capable of switching internally between an electrically connected state and an electrically non-connected state, wherein the conductive assembly is provided with a first electrical connection portion that is elastically deformable; and
a first voltage control member 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.
