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.
