装置。 An image forming apparatus that performs development by charging the surface of an image carrier with a corona discharge device and causing toner to adhere to the charges on the surface of the image carrier, includes a corona discharge device equipped with a high-voltage power source for corona discharge and a grid electrode, and the toner. The magnetic roll is provided with a magnetic roll for conveying and adhering the image to the surface of the image carrier, and a voltage setting means for the magnetic roll, and the voltage setting means divides the grid voltage applied to the grid electrode to the magnetic roll, and the voltage is set by the voltage setting means. An image forming apparatus characterized in that the output of the setting means is a bias voltage of the magnetic roll.
