置。toner concentration detection means for detecting the toner concentration of the developer;
a toner remaining amount detecting means for detecting the remaining amount of toner in the toner hopper, a toner replenishing means for replenishing toner from the toner hopper into the developer container, an operating means for operating the image forming apparatus, and a predetermined toner concentration detecting means. A reference value for toner density control is set based on the detected value at the time of operation, and the toner consumption amount is read out by comparing the detected value of toner density detected during operation of the image forming apparatus with the above reference value. control that outputs a replenishment signal to the toner replenishing means according to the value, and stops outputting the operating signal to the operating means when the remaining toner amount detecting means detects that the remaining amount of toner is less than a set value; 1. A toner density control device for an image forming apparatus, comprising: means.
