Abstract
In an image forming apparatus, a resistant layer of each writing electrode is formed substantially in a semi-circular convex shape projecting upwardly. The top of the resistant layer is a spherical surface so that the resistant layer is in point contact with the charged layer of the latent image carrier. Because of point contacts, foreign matters adhering to the surface of the latent image carrier are easily allowed to pass, thereby preventing the occurrence of filming on the surface of the latent image carrier.
