PROBLEM TO BE SOLVED: To enable a developing cartridge to be grounded between it and a device body by providing a device with a conductive part for grounding the developing cartridge between it and the device body when the developing cartridge is loaded in the device body. SOLUTION: A projection part 63g is provided with a conductive part 63g8 for grounding this developing cartridges for toner of magenta, cyan and yellow as nonmagnetic toner between it and a device body when the developing cartridges are loaded in the device body. The conductive part 63g8 is made of metal such as iron, for example and constituted of a sylindrically shaped portion conductive part 63g81 and a D-shaped cut portion 63g82. Then the conductive part 63g8 is press-fitted in the inside of a pin fitting part 63g1, a shutter fitting part 63g6 and a head part 63g7 so as to pierce through them in the longitudinal direction. Besides, the fitting part 63g1, the fitting part 63g6 and the head part 63g7 are the integral moldings made of plastic. |
