画像濃度制御装置。 The amount of toner consumed during development is detected by a current detection means provided in the development bias application circuit 11,
By controlling the rotation of the toner supply motor 20 according to this current value, the optimum toner supply rate is calculated for each copying machine in a device that replenishes the developing device 4 with an amount of toner commensurate with the toner consumed during development. In addition, various other parameters for controlling the toner supply motor 20 are calculated from the toner supply rate as a function of the toner supply rate.
An automatic image density control device for a copying machine, which controls the rotation of a copying machine.
