In an image forming apparatus comprising a latent image carrier and a writing means having a plurality of writing electrodes which are aligned in the axial direction of the latent image carrier and arranged in contact with or proximity to the latent image carrier to form an electrostatic latent image on the latent image carrier, the contact width of the writing means relative to the latent image carrier is set to be smaller than the contact width of any cleaning means, the width of a toner carrying portion of a developing means confronting the latent image carrier, the width of a transferring means, and the width of a charge removing portion of a charge removing means. In addition, the width of the writing means is set to be smaller than the width of the latent image carrier.
