ABSTRACT:
A web charging apparatus comprises wire electrodes, which are extended along the width of a moving web, and a grounded roller, on which the web is supported. A grounded plate is provided behind the wire electrodes relative to the grounded roller, so that the electrostatic potential at both widthwise ends of the web can be equal to the electrostatic potential at the central part of the web.
