Abstract

PURPOSE:To suppress the width of white picking out to a required minimum value, by changing the timing of applied voltage to a conductive carrying member according to the usage conditions such as nature of copy paper, environmental conditions and change of magnification. CONSTITUTION:A resist clutch signal (a) is added to a CPU control circuit 12 with a signal h from an input circuit 11 according to the factors of variance such as nature of copy paper, environs like temperature and usage conditions like copy magnification. A timing control circuit 9' is controlled with the output signal (a') of the circuit 12, which controls a copying and separation device and the internal part of the copy machine and outputs various control signals (i) based on the signal (h). If the signal h shows factors of unreliable separation, the start of application time to a conductive belt 6 is made longer to increase the separation force.
