Abstract:
An edge counter counts the number of edges satisfying a predetermined condition to provide an edge count. A pixel counter counts the number of pixels satisfying a predetermined condition to provide a pixel count. An image determination unit and a toner amount acquisition unit obtain a toner consumption amount based on the edge count and the pixel count for each area.
