PROBLEM TO BE SOLVED: To provide an image forming device in which during the execution of a RDH (a circulation type manuscript feeding device) mode, in the case that other copy mode is interrupted, time to interruption processing is shortened, and return of the preceding RDH mode is hastened, and an operator is not confused by the interruption of other copy mode. SOLUTION: During the execution of an RDH mode in which a manuscript is carried with an RDH 3 and an image is formed on a sheet member, when an SDH (a manuscript feeding device) manuscript detecting sensor 94 detects the placing of the manuscript in an SDH 4, in the case that the number of manuscripts detected with an SDH circulation detecting sensor 99b is smaller than that of interruption permission values, the RDH mode is discontinued, and an SDH mode in which the manuscript is carried with the SDH 4 and an image is formed on the sheet member is started. |
