An image forming apparatus includes an image display that displays an image. In response to determining both that the image display is present in a detected user's gaze direction and that a distance between the user and the image display is shorter than a predetermined distance, the apparatus performs a change process on the image. After performing the change process, the apparatus determines whether or not the distance between the user and the image display is equal to or greater than the predetermined distance, and if so, returns the image back to a state prior to the change process.
