Abstract
If it is desired to display the number of copies which can be outputted corresponding to the defined capacity of a developer which is determined by an image forming apparatus, a document which is thought to have a substantially average black ratio of the respective black ratios of images actually recorded by the image forming apparatus is prepared. The prepared document is set in reading means. An image of the set document is read by reading means. The black ratio of the image of the document is calculated on the basis of an output of the reading means. The number of copies which can be outputted corresponding to the defined capacity of the developer which is determined by the image forming apparatus is calculated on the basis of the calculated black ratio. The calculated number of copies which can be outputted is displayed.
