An image forming apparatus includes a microcomputer which controls components for executing an image forming operation, and sends a signal to a supervising portion when no abnormality occurs in itself. The supervising portion includes a watch-dog timer, and sends a reset signal to the microcomputer when the signal from the microcomputer is not continuously inputted for a predetermined time period or more. Accordingly, the microcomputer becomes in a reset state, and the image forming operation is stopped. A flag is not set until a predetermined time period elapses from a time that the reset signal is inputted, and therefore, the image forming operation is inhibited for the predetermined time period.

In a copying machine, an original which has been once exposed to be scanned is inverted and transmitted again to an original table glass, and a sheet having one face onto which an image has been fixed is inverted and then transmitted through a transmitting path to an image forming section, whereby the top and back faces of the original are copied to the top and back faces of the sheet, respectively.
