Abstract
An image forming apparatus includes a latent image carrier to carry a latent image on a surface thereof, a developing device to develop the latent image with toner to form a toner image on the surface of the latent image carrier, a transfer unit to transfer the toner image onto a recording medium, and a controller. The controller executes an image density adjustment control of adjusting a developing bias to obtain a target image density. The controller further executes a forced toner consumption control of forcibly consuming the toner contained in the developing device by attaching the toner to the latent image carrier to form a toner pattern on the surface of the latent image carrier. The controller executes the forced toner consumption control to forcibly consume a smaller amount of toner in response to a higher developing bias as adjusted by the image density adjustment control.
