Abstract:
An image forming apparatus has an image acquisition portion that acquires image data on an image including a character. A character-periphery detector detects the peripheral part of the character in the image data acquired by the image acquisition portion. An outline emphasis portion sets the density of the image data acquired by the image acquisition portion, so that the density of the peripheral part of the character detected by the character-periphery detector becomes higher than the density indicated by this image data. A density changer sets the density of the image data so that this density gradually becomes lower from the peripheral part of the character detected by the character-periphery detector toward the inside thereof. An image former forms an image on a sheet of recording paper on the basis of the image data whose density is set by the outline emphasis portion and the density changer.
