An image forming apparatus includes an image forming unit that forms an image to be formed on a recording medium. The image formed by the image forming unit has a size larger than a size of the recording medium that is transported, the image forming unit causing the image to adhere to the entire area of the recording medium. A width of the image in a direction substantially orthogonal to a transporting direction of the recording medium increases from a front end toward a rear end of the recording medium in the transporting direction of the recording medium.
