<p>An image forming apparatus (100) includes a latent image carrier (2) to carry a latent image, a developing device (5) to develop the latent image with toner to form a toner image on the latent image carrier (2), a transfer unit (6) to transfer the toner image onto a recording medium, and a controller (30). The controller (30) executes an image density adjustment control of adjusting a developing bias to obtain a target image density, and further executes a forced toner consumption control of forcibly consuming the toner contained in the developing device (5) by attaching the toner to the latent image carrier (2) to form a toner pattern on the surface of the latent image carrier (2). The controller (30) 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.</p>
