PROBLEM TO BE SOLVED: To provide an image forming device constituted capable of affording convenience to an operator and preventing the futile copying action when an original is not supplied in parallel. SOLUTION: At the time of a parallel paper supply mode, center elimination is set and it is judged whether a start key is turned on or not (S1-S3). When the start key is turned on, it is judged whether both original set sensors are turned on or not. When both of them are turned on, the original is supplied in parallel and copied on one transfer paper (S4 and S5). When one original set sensor is turned on, the copying action is stopped once and a warning is displayed (S7). Thereafter, the additional copying action of the original (S8 and S5), the cancel of the copying action of the original (S10) or such a copying action that only one surface is copied and the other surface is erased (S11) are executed by the selection of the operator. |
