<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that forms toner images including thin lines with suppressed toner scattering. <P>SOLUTION: An image forming apparatus forms solid patch images 601y, 601m, 601c, 601k, and thin-line patch images 602y, 602m, 602c, 602k with the use of image forming units StY, StM, StC, StK; and then corrects a signal level of a thin-line area based on the average toner height Rave, which is calculated from toner heights of the solid patch images Ht1y, Ht1m, Ht1c, Ht1k, and toner heights of the thin-line patch images Ht2y, Ht2m, Ht2c, Ht2k. <P>COPYRIGHT: (C)2012,JPO&INPIT |
