Abstract:
1. An image forming apparatus comprising: an electrostatic latent image carrier configured to carry an electrostatic latent image; a developing device configured to visualize the electrostatic latent image utilizing a two-component developer; a supply device configured to supply toner according to a change in toner density of toner contained in the two-component developer inside the developing device; and a control device having an input side connected to a density sensor configured to detect a value of the toner density and an image information acquisition device configured to acquire information on an image formed on the electrostatic latent image carrier, and an output side connected to a driving device configured to drive the supply device, wherein the control device is configured to store a target value of the toner density, the control device including wherein when the control device obtains a comparison result indicating that the detected value is higher than the target value, the control device performs control to stop the driving device, or performs control to drive the driving device to supply toner in an amount less than a combined toner supply amount obtained by adding the first toner supply amount and the second toner supply amount.
