An image forming apparatus such as a laser beam printer has a laser mechanism, an optical system for forming a latent image on a photosensitive drum, a separation charge eliminator for separating a transfer material with a toner image transferred thereonto from the drum, and a printer controller for controlling the print operation. A high voltage is applied to the charge eliminator for a non-image zone of the original, and a low voltage is applied for an image zone of the original. The application voltage for the charge eliminator is obtained by superposing a DC voltage on an AC voltage. A system including a reader, a CCU, and a printer is also provided.
