An image-forming apparatus includes an image carrier that has an electrically chargeable film formed on a surface thereof and that carries an image and a charging section that charges a surface of the film on the image carrier. The charging section includes a first charging member that applies a direct-current voltage between the first charging member and the image carrier and a second charging member that applies a direct-current voltage between the second charging member and the image carrier to charge the film on the image carrier to a predetermined surface potential after the first charging member charges the film on the image carrier. The voltage applied by the first charging member is decreased such that the surface potential of the image carrier after the voltage is applied by the first charging member is decreased as the film on the image carrier becomes thinner. |
