ABSTRACT:
An image forming apparatus capable of settling such problem as an error between a cumulative developer consumption calculated on the basis of image information inputted into a exposing device and an actual developer consumption, which occurred due to fog. The image forming apparatus changes inputted image information into binary image information, exposes photosensitive body on the basis of the binary image information, forms a developer image on record medium, and comprises an exposure picture element number counting section for counting picture element number of exposed picture elements in all picture elements to constitute the binary image information; a print condition detecting section for detecting appointed print condition; a revision information storing section for storing revision information on the basis of the print condition; and a developer quantity calculating section for calculating a developer consumption on the basis of the picture element number counted by the exposure picture element number counting section, the print condition detected by the print condition detecting section, and the revision information stored in the revision information storing section.
