Abstract
A full-color image forming apparatus, in which an image formed by plural electrophotographic processing portions arranged along a conveying belt is superposedly transferred in order onto a recording medium conveyed by the conveying belt, and thereby the color image is obtained on the recording medium, is capable of obtaining high-quality output and suppressing the positional displacement of the respective colors. When the adjustment of the positioning is performed between the n (n≧2) colors, the calculation and the compensation of the positional displacement is performed such that the displacement amount of the respective n colors falls in the area within (n−1)·R/n by use of the CPU 121.
