<P>PROBLEM TO BE SOLVED: To obtain an accurate added value for image data to be written in each light source by selecting and acquiring an added value which is a counted value of the number of pixels from a plurality of LUTs in accordance with image data to be written in each light source. <P>SOLUTION: An image forming apparatus for simultaneously writing a plurality of lines on a photoreceptor by a plurality of light sources as a latent image of image data developed like a bit map and developing the latent image by toner to output an image is provided with a plurality of counters for counting the number of pixels to be written and constituted so as to calculate toner consumption by acquiring a predetermined added amount corresponding to the value of many-valued image data from a reference table in counting is also provided with an LUT 111, adders 112, 113 and a counter 114 to count the number of pixels to be written in each light source by each counter. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
