An image forming apparatus includes an image forming unit, a sensor, and a controller. The image forming unit is configured to form a toner image on an image carrier based on image data and transfer the toner image on the image carrier onto a sheet. The sensor is positioned to measure an amount of toner on the image carrier before or after transfer of the toner image onto the sheet. The controller is configured to determine a remaining amount of toner that is discarded or wasted based on the measured amount.
