ABSTRACT:
A disclosed image forming apparatus for detecting position displacement patterns and correcting position displacement of an image forming position in a main scanning direction according to the detection result, includes a position displacement amount calculating part configured to calculate the amount of the position displacement according to the detection result, a position displacement correcting part configured to correct the position displacement by performing at least one of multiplication correction or multiplication error deviation correction, a correction amount calculating part configured to calculate a multiplication error deviation correction amount for correcting multiplication error deviation generated by the multiplication correction, a first determining part configured to determine whether to plot a first position displacement correction pattern included in the position displacement patterns for performing the multiplication error deviation correction according to the multiplication error deviation correction amount, and a plotting part configured to plot the position displacement correction patterns.
