<p>The present image forming apparatus forms a reference developing material image on an image carrier using an exposure unit and a developing unit before executing auto tone correction processing, and detects the density of the reference developing material image formed on the image carrier. If the detection result indicates that the toner charge amount of the developing material contained in the developing unit is within a predetermined range, auto tone correction processing is executed, whereas if the detection result of the density detecting unit indicates that the toner charge amount of the developing material contained in the developing unit is outside the predetermined range, adjustment processing for adjusting the toner charge amount of the developing material contained in the developing unit to be within the predetermined range is executed before execution of auto tone correction processing.</p> |
