Abstract: PURPOSE:To make to fog due to superposed pattern generated at an image boundary area inconspicuous by changing the modulation amount of the superposed pattern in accordance with a distance from the boundary of an image part at the time of superposing information peculiar to an image forming device with a color image. CONSTITUTION:A machine number pattern generation circuit 2015 generates an information pattern peculiar to the device. An ITOP generation circuit 2113 decides the modulation amount by referring to a signal showing the image area of a recording member, namely, a reference signal at the write position of the image. A modulation amount control circuit 2016 changes a pattern signal generated by the machine number pattern generation circuit 2015 in accordance with the decided modulation amount, and a comparison circuit 2017 superposed the pattern signal with the density signal of the image so as to synthesize them. Namely, the modulation amount is set to zero at the image write position from the generation signal of the ITOP generation circuit 2013, and the modulation amount is increased according as it parts from a boundary surface. Thus, the fog due to superposed patterns at the image write position can be made inconspicuous.
