Abstract
PURPOSE: To perform reproduction of correct images by maintaining the corona current flowing in the a corona discharger for transfer always constant and controlling the toner transferred from photoreceptor to transfer paper to a constant quantity at the set value of transfer voltage.
CONSTITUTION: A detector 23 receives the current IT flowing in the charge wire 5A of a corona discharger 5 for transfer from a power source 20 and the current IC flowing simultaneously in the casing 5B of the discharger 5 as its 2 inputs and detects the difference between said both current values. The output of the detector 23 is inputted to a comparing amplifier 22, where it is compared with a reference value E0. The output of the comparing amplifier 22 is inputted to a controller 21, and the current of the discharger 5 is so corrected and controlled by this controller 21 as to return to the state at the original corona discharge current.
