Abstract
An apparatus for controlling the supply of a developing agent, installed in a developer, is equipped with a developing-agent amount detector to detect an amount of the developing agent consumed by the developer; a driving-time detector to detect a driving time for actually shaking the developing agent provided in the developer; a developing-agent density calculator to calculate an actual density of the developing agent in the developer based on the consumed amount of the developing agent detected by the developing-agent amount detector and the actual driving time detected by the driving-time detector; a developing-agent amount controller to compare the actual density detected by the developing-agent density calculator and a reference developing-agent density to perform forcible supply of the developing agent when the actual density is lower than the reference density whereas forcible consumption of the developing agent when the actual density is equal to or higher than the reference density; and a consumed-amount adjuster to adjust the consumed amount of the developing agent per unit of time under control by the developing-agent amount controller.
