Abstract
The image forming apparatus includes an image carrier, a charging unit, an exposure unit, a developing unit, a transfer unit, a cleaning blade, and a controller. The controller detects printing-coverage rates on a basis of plural areas divided in the longitudinal direction of the image carrier. At a specified timing, the controller executes aging process in which the image carrier in a charged state is driven into rotation under light irradiation by the exposure unit. For the aging process, the controller sets a condition that a light quantity of the exposure unit for an area of larger coverage rate is larger than a light quantity of the exposure unit for an area of smaller coverage rate.
