ABSTRACT:
A method and apparatus for corona-charging a charge-receiving member having image frames used in recording, such as in electrostatographic recording. In the method and apparatus there is synchronizing movement of the charge-receiving member with the application of different voltages to the corona-charging apparatus. Thus, during a transition period when a region of the charge-receiving member that is adjacent a leading edge of an image frame is aligned with the charging apparatus, an element of the charging apparatus is provided with an overcharge voltage level substantially higher than a voltage level suitable for achieving on the image frame an aim point voltage level to which the image frame is to be charged to provide a relatively rapid rate of charge deposition on the charge-receiving member. The voltage on the element is thereafter adjusted to a lower voltage level suitable for achieving an aim point voltage level on the image frame. The element is preferably a grid but may be a corona-charging wire.
