Abstract
An image forming apparatus includes a latent image bearer, a developing device, a supplier, and a controller. The controller controls the supplier according to a detection result of a toner density by the toner density sensor and a toner density target value to adjust the toner density of developer in the developing device. The controller is configured to correct the toner density target value and an imaging condition affecting a toner adhesion amount of an output image separately from the toner density, according to a component adhesion deterioration degree being a deterioration degree of carrier due to adhesion of a toner component, obtained based on at least an average image area ratio of the output image, and a coating abrasion deterioration degree being a progression degree of deterioration due to coating abrasion of the carrier, obtained based on at least the average image area ratio of the output image.
