Abstract
In an image forming apparatus, even when power supply to the apparatus is stopped, it is possible to let the user recognize that an electronic file to be used has been erased, and that a necessary electronic file will be erased when the apparatus is to be used after next power on, so that wasteful power supply to the apparatus can be reduced. When the power is shut off, an auto-erased file list or a to-be-erased file list is displayed on electronic paper 108, in accordance with display setting contents set by the user before power off.
