Separating device for image forming apparatus

摘要

A separating corona discharger 40 is provided with a first separating discharge wire 42 and a second separating discharge wire 43. The wire diameter of the first separating discharge wire 42 is set to, for example, 60 mu m, and the wire diameter of the second separating discharge wire 43 is set to, for example, 100 mu m. The first separating discharge wire 42 and the second separating discharge wire 43 are connected in parallel to an AC high-voltage power supply of a constant current type at the offset current. Accordingly, a large number of minus current components flow from the AC high-voltage power supply 46 into the discharge wire 42 having a small wire diameter from which discharge having minus components is easily induced, to obtain a desired distribution of a discharge having a large number of minus current components.
