Abstract
An image forming apparatus forming has a resume device to resume a situation when the power supply was turned off. Further, a timer is provided to count a period after the power supply was turned off. A controller inhibits operation of the resume device when the timer counts up a predetermined period. Further, an interrupting device is provided, and when the image forming apparatus is in a predetermined state such as paper empty, the image forming apparatus is operated according to the image forming information entered by the interrupting device. In a different way, an image forming apparatus has a switching device to turn off manually the power supply. After the power supply was turned off with the auto-power-off function, if the power supply is turned on manually, data on image forming saved in a memory are cleared. Thus, a new user can start a copy job readily, while the secrecy of image data of a previous user can be maintained.
