摘要： In an image forming apparatus of the present invention, a resistant layer 13 of each writing electrode 3b is formed substantially in a semi-circular convex shape projecting upwardly. Therefore, the top of the resistant layer 13 is a spherical surface so that the resistant layer 13 is in point contact with the charged layer 2d of the latent image carrier 2. Because of point contacts, foreign matters adhering to the surface of the latent image carrier 2 are easily allowed to pass, thereby preventing the occurrence of filming on the surface of the latent image carrier 2.
