PROBLEM TO BE SOLVED: To provide a technology capable of suppressing a latent image ghost. SOLUTION: Two image data inputted respectively into an aligner 19 before and after a photosensitive drum 20 turns once are defined as first image data and second image data, respectively. The correspondence relationship between a correction for correcting the second image data, a value of the first image data and a value of the second image data is stored in one-dimensional LUTs 201, 202 so that a concentration of an image to be transferred onto a record medium when the second image data is inputted into the aligner 19 is approximated to a concentration of an image displayed by the second image data. A correction deciding circuit 102 decides a correction corresponding to the value of the first image data and the value of the second image data based on the correspondence relationship stored in the one-dimensional LUTs 201, 202. An adder 103 corrects the second image data inputted into the aligner 19 by using this correction. COPYRIGHT: (C)2009,JPO&INPIT |
