Abstract
An image forming apparatus includes a latent image carrier carrying a latent image, a developing device visualizing the latent image utilizing a two-component developer, a supply device supplying toner according to a change in toner density in the two-component developer inside the developing device, and a control device having an input side connected to a density sensor detecting a value of the toner density and an image information acquisition device acquiring information on an image formed on the latent image carrier, and an output side connected to a driving device driving the supply device. When the detected value is higher than a target value of the toner density stored by the control device, the control device performs control to stop the driving device or drive the driving device to supply toner in an amount less than a combined toner supply amount of first and second toner supply amounts.
