像を行う現像装置において、磁性粒子とトナーよ
り成る現像剤の混合部と、トナーのホツパー部と
を仕切る壁のトナー補給窓をメツシユ構造窓とし
、そのトナー補給窓に設けた窓開閉部材を、上記
混合部内の現像剤の片寄りによつて作動させるこ
とにより、トナー補給窓面積を増減させてトナー
補給量の制御を行うことを特徴とする現像装置。 In a developing device that performs development by arranging a developing sleeve to face a photoreceptor drum, the toner replenishing window in the wall that partitions a developer mixing area consisting of magnetic particles and toner from a toner hopper area is a mesh structure window. A developing device characterized in that the toner replenishment amount is controlled by increasing or decreasing the toner replenishment window area by operating a window opening/closing member provided in the toner replenishment window by shifting the developer in the mixing section. .
