An image forming apparatus includes a display unit which outputs image data in the form of a complete image, a photosensitive medium which forms an electrostatic latent image corresponding to the image outputted from the display unit, a developing unit which develops the electrostatic latent image formed on the photosensitive medium, a transfer unit which transfers the developed image of the photosensitive medium onto a printing medium, and a fixing unit which fixes the transferred developed image in the printing medium.
