IMAGE FORMING APPARATUS

An image forming apparatus includes an image forming unit for forming an image on a recording medium, a fixing unit for fixing the image on the recording medium, a storage unit configured to store image data representing the image, a first generation unit for generating a first position information which represents a position of a target pixel in a first direction which corresponds to a conveyance direction of the recording medium. The apparatus further includes a second generation unit for generating a second position information which represents a position of the target pixel in a second direction which is perpendicular to the first direction; a setting unit for setting, based on magnification changing information in the first direction which corresponds to a conveyance direction of the recording medium, a division condition for dividing the image data representing the image into two or more areas in the first direction.
