<P>PROBLEM TO BE SOLVED: To accurately calculate the quantity of toner consumed for image formation, in an image forming apparatus that forms an image, using the toner. <P>SOLUTION: In a color conversion section 114, image data (input image data), immediately after RGB image data are color-converted into CMYK image data corresponding to toner colors, are integrated by a first counter 201. Output image data, after data-processing via a gradation correcting section 115 and a half-toning section 116, are integrated by a second counter 202. On the basis of selection information output from a CPU 111 according to the contents of data processing, either of the outputs of the two counters is selected. An integral value, corresponding to a selected one page is multiplied by a coefficient KO, then an offset value Coff is added to this result, and the thus obtained value is used as the quantity of toner consumption. <P>COPYRIGHT: (C)2007,JPO&INPIT |
