Patent ID: 8264737

Claim:
An image forming apparatus comprising: a rotational image carrier; an image forming unit configured to form a latent image on the image carrier in a main scanning direction substantially perpendicular to a rotational direction of the image carrier, to develop the latent image as a toner image, and to transfer the toner image onto a recording medium, to thereby form an image on the recording medium; a determining unit configured to determine a position of a margin region, on which the toner image is not formed in the main scanning direction with respect to a rotational direction of the image carrier, based on input image data; and a magnification correcting unit configured to correct the input image data in order to correct magnification of the image with respect to the rotational direction of the image carrier, wherein the magnification correcting unit is configured to increase a width of the margin region with respect to the rotational direction of the image carrier in order to expand the magnification of the image with respect to the rotational direction of the image carrier, and to reduce the width of the margin region with respect to the rotational direction of the image carrier in order to reduce the magnification of the image with respect to the rotational direction of the image carrier.
