Abstract

A toner replenishing device for replenishing toner to a toner storage area, from where the toner is supplied to a developing section, includes a holder for releasably holding a cartridge containing therein a quantity of toner, which may be located at a cartridge mounting and dismounting position and at a replenishing position, in which the cartridge is held substantially horizontally and driven to rotate thereby discharging the toner to a toner transporting path leading to the toner storage area. The cartridge is provided with a first mating member and the holder is provided with a second mating member corresponding in position to the first mating member. Thus, only the cartridge having the first mating member may be properly held by the holder for carrying out a toner replenishing operation.
