The object of the present invention is to provide an image forming apparatus which can forms a high-quality image with high resolution while stabilizing potential and size of an electrostatic latent image and in which the wearing of electrodes and a latent image carrier can be reduced, thereby improving the durability thereof. The image forming apparatus comprises a latent image carrier 2 and a substrate 3a on which a plurality of writing electrodes 3b are formed along the axial direction of said latent image carrier. The latent image carrier 2 and the substrate 3a are arranged in elastic contact with each other so as to form an electrostatic latent image on the latent image carrier 2.
