Abstract
A step and non-uniformity in density in a drawing object due to an offset for an electrical color-shift correction are reduced. An image forming apparatus includes: a unit for determining a changing coordinate in a main scanning direction for correcting a color shift; a unit for detecting a closed region lying across the determined changing coordinate, from a drawing object; and a unit for performing a changing by using the determined changing coordinate without changing a shape of the detected closed region.
