Abstract
PURPOSE:To perform always optimum toner replenishment irrespective of toner consumption and eliminate uneven concentrations by detecting developer concentration at every copying, determining toner replenishment time, i.e., rate of replenishment, according to the detected concentrations and replenishing the toner by sharing the rate of the replenishment thus determined.
