Abstract
An image forming apparatus includes a calculation portion that calculates an image ratio of the electrostatic image to be formed. A controller controls developer supply from a developer supplier to a developing unit based on the toner density output of an inductance sensor. An adjustment portion adjusts the density of the toner output from the toner density detection portion to a higher value in a case where the image ratio calculated by the calculation portion is higher than a predetermined image ratio.
