An image forming apparatus includes a data processor, a first calculating unit, a second calculating unit, an updating unit, and an instructing unit. The first calculating unit calculates estimated developer consumption necessary to form an image. The second calculating unit calculates developer consumption corresponding to a sum of density values of image pixels. The updating unit calculates remaining developer. The instructing unit issues an instruction to the data processor to reduce developer to be consumed when the estimated developer consumption exceeds the remaining developer. The data processor converts scanned image data into print image data in response to the instruction such that the image is to be formed with the remaining developer.
