摘要： In the case that images having high coverage ratios are printed out continuously in a trickle developing apparatus that uses a two-component developer, the developing apparatus judges how much carrier is accumulated inside a developer tank beyond the discharge level of a trickle discharging mechanism and carries out appropriate processing before the developer overflows over a regulating gap. The developing apparatus, having stirring members for conveying and stirring a developer-tank-contained developer and a developer holder, comprises a developer replenishing tank; a discharging mechanism for discharging an excessive amount of the developer-tank-contained developer outside the developer tank when the amount of the developer-tank-contained developer inside the developer tank has exceeded a predetermined amount; and calculating device for calculating the amount of the carrier existing inside the developer tank, and carries out predetermined danger avoiding operation when it has been judged using the calculating device that the integrated value of carrier obtained by integrating the amount of the carrier existing inside the developer tank is likely to exceed a predetermined excessive accommodation amount of carrier.
