ABSTRACT:
A developing apparatus operable with a toner cartridge having a flexible sack which is filled with a toner. When the toner cartridge is mounted on a developing tank included in the apparatus, the sack having been held under tension by the toner is perforated to form a hole therein. The hole causes the sack to contract rapidly due to its contactability while forcing the toner out of the sack. Then, the toner is dropped or otherwise auotmatically supplied into the developing tank. This allows the toner to be supplied without resorting to any extra manual operation after the toner cartridge has been mounted on the tank.
