ABSTRACT:
An image forming apparatus includes a charging device that, by allowing a brush roller to be rotated so as to be set in contact with a surface of a photosensitive body, charge the surface of an image carrier, a light exposure device that radiates image information light onto the surface of the image carrier to form an electrostatic latent image, a developing device that develops the electrostatic latent image into a developing agent image, a transfer device that transfers the developing agent to a sheet, and a guide device that guides an outer periphery of the brush roller so as to prevent the image information light from being blocked by the brush roller.
