Abstract:
A toner consumption-calculating apparatus includes a printed portion area-detecting unit that detects an area of a printed portion of image data of a latent image that is formed on a latent image-bearing member; a latent image portion area-detecting unit that detects an area of a latent image portion on the latent image-bearing member; and a latent image portion toner consumption-calculating unit that calculates latent image portion toner consumption that indicates toner amount that is consumed due to adhering on the latent image portion. The latent image portion toner consumption-calculating unit uses a detection result of the latent image portion area-detecting unit and a detection result of the printed portion area-detecting unit to calculate the latent image portion toner consumption.
