PURPOSE:To always execute stable transfer paper separation without generating separation failure, by providing a means for controlling so that an interval of each transfer paper exceeds an interval of a separating corona discharger and a flash fixation device. CONSTITUTION:When the rear end of sheetlike transfer paper passes through a switch 21, an output of an inverter INV1 becomes a low level, this fall is detected by a differentiating circuit consisting of a resistance R4 and a capacitor C3, and a timer T2 is triggered. When operation of the timer T2 is ended, an output of INV4 becomes a high level, it is detected by a differentiating circuit consisting of a resistance R7 and a capacitor C5, and an FF1 is reset through an OR circuit OR1. Accordingly, a magnet clutch CMC1 and a lamp L1 operate again, an inserting roll 20 rotates, and the following sheetlike transfer paper can be inserted. The operating time of the timer T2 is decided by a minimum necessary carrying interval of the sheetlike transfer paper, and is set to the time when the transfer paper is carried by a distance L1 from an outlet of a flash fixation device 35 to the center of a separating corona discharger 31, or a longer time than said time. In this way, stable transfer paper separation can be executed at all times. |
