Abstract
When an image forming process is a prescribed process consuming toner rapidly, the toner is supplied at any time besides the normal toner supply timing. Therefore, the toner is supplied frequently, the period of normal toner supply timing in which a large amount of toner is supplied becomes longer, and the toner is well mixed with the developer. When the image forming process is a prescribed process consuming toner rapidly, the period of determining toner concentration is made shorter. Consequently, the number of toner replenishment is increased, and the fluctuation of the toner concentration in the developer becomes small.
