Abstract:
1. A developing apparatus for developing an electrostatic image by means of colored toner and transparent toner, comprising: a developing device for color receiving the colored toner and a carrier and developing the electrostatic image; a developing device for transparence receiving the transparent toner and a carrier and developing the electrostatic image; a developer replenishment container for color receiving a replenishment developer for color containing at least the colored toner and the carrier, the developing device for color being replenished with the replenishment developer for color; a developer replenishment container for transparence receiving a replenishment developer for transparence containing at least the transparent toner and the carrier, the developing device for transparence being replenished with the replenishment developer for the transparence, wherein the replenishment developer for transparence having a carrier weight ratio lower than a carrier weight ratio in the replenishment developer for color; a developer discharge aperture for color arranged in the developing device for color and discharging a developer in the developing device for color to an outside of the developing device for color in association with replenishment with the replenishment developer for color; and a developer discharge aperture for transparence arranged in the developing device for transparence and discharging a developer in the developing device for transparence to an outside of the developing device for transparence in association with replenishment with the replenishment developer for transparence.
