Abstract:
1. An image forming apparatus comprising: a latent image carrier to carry a latent image on a surface thereof; a developing device containing a two-component developer including toner and carrier charged to a predetermined polarity, to electrostatically attach the toner to the latent image with a developing bias to form a toner image on the surface of the latent image carrier, a transfer unit to transfer the toner image from the surface of the latent image carrier onto a recording medium; a controller to execute an image density adjustment control of adjusting the developing bias to obtain a target image density at a predetermined time, and further execute a forced toner consumption control of forcibly consuming the toner contained in the developing device at a predetermined time by attaching the toner to the latent image carrier to form a toner pattern on the surface of the latent image carrier, the controller executing 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.
