Abstract
An image forming apparatus is disclosed that is able to improve transfer efficiency and image quality. The image forming apparatus includes an organic photo-conductor with latent images formed thereon, and a developing unit for developing the latent images. The organic photo-conductor has surface friction coefficient less than or equal to 0.3. The developing unit develops the latent images while transporting a two-composition developing agent including a toner T and a carrier C by a traveling wave electric field.
