PURPOSE:To prevent toner from dispersion at the feeding of the toner and to prevent a copying machine from its inside dirt by dipping a feeding hole of a hopper for storing a feeding toner and a feed roller lower than the upper surface of a developer stored in the storing part. CONSTITUTION:The hopper 13 as a toner feeding means is arranged on the upper part of a case 1 and projected stripes expanded in the axial direction are formed on the surface of the feed roller 18. To feed the toner 15, the roller 18 is rotated and the toner of the quantity corresponding to the rotated angle of the roller 18 is fed from the feeding hole 17 to the two-component group developer 2 in the storing part 3. Since the feeding hole 17 of the hopper 13 and the roller 18 are dipped lower than the upper surface of the developer 2, the toner 15 can be prevented from being dispersed and leaked to the outside of the case 1 of the developing device and the inside of the machine can be prevented from dirt. |
