In an image forming apparatus including software buttons and hardware buttons, a log-in image is displayed, and when input of a log-in name by a user is completed, determination is made as to whether an operation device used at that time is hardware buttons. If the operation device is hardware buttons, the image forming apparatus erases a software keyboard from a display panel, and if the operation device is not the hardware buttons, turns off a hardware button lamp. |
