Abstract: An image forming apparatus and a cartridge to be used therein. The image forming apparatus includes a main casing, a CPU, and a main electrode. The cartridge accommodating therein toner is attachable to and detachable from the main casing, and has a cartridge electrode electrically connectable to the main electrode, a moving member and a pressure member. The CPU is configured to judge assembly or non-assembly of the cartridge with respect to the main casing and to judge whether or not the assembled cartridge is a new cartridge. The moving member is movable by a predetermined moving amount to permit the pressure member to be movable. The cartridge electrode is movable in accordance with the movement of the pressure member. As a result of a movement of the main electrode in accordance with the movement of the cartridge electrode, the CPU determines that the assembled cartridge is a new cartridge.

Abstract: A developing cartridge that maintains a pressing condition to press a developer carrier against the image carrier is described. The developing cartridge may include a coil spring that presses the developer carrier against the image carrier. The coil spring may include a handle that transmits a pressing force to the coil spring via the contacting member. By doing so, every time the developing cartridge is replaced, a new coil spring and handle can be provided for the color laser printer with the developing cartridge attached. Therefore, a constant pressure by the coil spring can be continuously maintained. Thus, a preferable pressure condition of the developer carrier against the image carrier can be continuously maintained.

Abstract: In an image forming apparatus, a cartridge has a cartridge side electrode. A main casing has a main casing side electrode. The cartridge includes a moving member that allows the main casing side electrode to be located at a connection position when the moving member is at a first position, to be located at a disconnection position when the moving member is at a second position, and to be located at the connection position when the moving member is at a third position. A determining unit determines that the cartridge's state is new if the determining unit detects that the main casing side electrode is electrically connected to the cartridge side electrode, then the main casing side electrode is electrically disconnected from the cartridge side electrode temporarily, and then the main casing side electrode is again electrically connected to the cartridge side electrode.
