PURPOSE:To prevent data on image formation conditions which are stored continuously from the start of an interruption mode from being cleared by providing a means which inhibits the specification of a power saving mode by a power saving mode specifying means in interruption mode. CONSTITUTION:Even when a power saving key 74 is turned on in interruption mode, that is not accepted, but accepted only not in interruption mode. Namely, an interruption key 72 is provided for the necessity of urgent copying operation and when the interruption key 72 is pressed during the copying of some original, a microcomputer interrupts the copying operation to enter the interruption mode, turning an interruption display device 73. At this time, the microcomputer transfers the current condition data on the quantity of copies, copy magnification selection, etc., to another memory so as to carry on the interrupted copying operation again. Consequently, even if the power saving mode is specified by mistake, the interrupted image forming operation is continued normally. |
