Abstract
In the light amount correction in the main scanning direction, sets of correction values of black and cyan for which the reflection frequency of optical elements are equal to an even number of times are made common to each other (a correction value set—KC), and sets of correction values of magenta and yellow for which the reflection frequency of optical elements are equal to an odd number of times are made common to each other (a correction value set—MY), whereby sets of correction values stored in a correction value storage portion in a correction value setting portion are reduced to two sets. Furthermore, in connection with this, the number of DA converters is reduced to two DA converters of a DA converter—K, C and a DA converter—M, Y.
