Abstract
A detection unit detects a color registration pattern formed on a transfer member. A first correction unit detects an amount of color misregistration, relative to a forming position of a color pattern having a reference color, of a forming position of a color pattern having another color and determines an offset value for adjusting a write start timing of the other color. A measuring unit measures the inclination of the transfer member. A second correction unit determines, according to the inclination, an offset value for adjusting the write start timing of each of the plurality of image forming units and for adjusting, relative to the write start timing of a reference color, the write start timing of another color. The reference color for the first correction unit is different from the reference color for the second correction unit.
