Abstract
An image forming apparatus includes an image area determining unit and an image processing unit. The image area determining unit is configured to determine a character edge area and a character inside area in an input image. The image processing unit is configured to be capable of performing (a) an inward expansion process for a pixel belonging to the image inside area, the character expansion process performed inwardly from the character edge area and (b) an outward expansion process for a pixel belonging to the character edge area, the outward expansion process performed outwardly from the character inside area. Further, the image processing unit selects the inward expansion process and/or the outward expansion process in accordance with an average brightness value of pixels belonging to the character inside area, and performs the selected the inward expansion process and/or the outward expansion process.
