<P>PROBLEM TO BE SOLVED: To compensate for deterioration of each light-emitting element with the lapse of time, without complicating the constitution of an image forming apparatus. <P>SOLUTION: Each image forming apparatus 20 includes a plurality of light-emitting elements E forming a latent image by exposure on a photoreceptor drum 242; and a control part 22 controlling the luminance of each light-emitting element E based on image data to designate luminance and correction data to correct the luminance. The control part 42 of the managing device 40 acquires use frequency data showing the degree of light emission of each light-emitting element E in the past from each of the plurality of image forming apparatuses 20 via a communications network N, and generates the correction data of each image forming apparatus 20, based on the use frequency data. Furthermore, the control part 42 transmits the generated correction data to each image forming apparatus 20 from the communications network N. <P>COPYRIGHT: (C)2007,JPO&INPIT |
