Abstract: An image forming apparatus includes a main casing, a cartridge, and a CPU. The main casing includes a detection electrode. The cartridge which accommodates toner therein, is attachable to and detachable from the main casing, and has a cartridge electrode electrically connectable to the detection electrode, and a moving member supported to the cartridge electrode. The moving member is movable from a first position where an electrical connection between the cartridge electrode and the detection electrode is interrupted to a third position where the electrical connection is interrupted via a second position where the electrical connection is established. The CPU is configured to judge whether or not the assembled cartridge is a new cartridge. The CPU determines that the assembled cartridge is new when the electrical connection is first interrupted, and established, and then interrupted in accordance with the movement of the moving member.
