An image forming apparatus includes a latent image forming portion for forming an electrostatic latent image corresponding to image information on an image bearing member, a developing portion, having a developer container for accommodating a developer containing a toner and a carrier, for developing the electrostatic latent image with the toner, and a toner density detecting portion for detecting a toner density in the developer container, a toner replenishment amount to the developer container being controlled in accordance with a result of detection by the toner density detecting portion, wherein a toner replenishment amount target value used for controlling the toner replenishment is controlled to fall within a restriction range, and the restriction range can be changed according to the image information.
