An image forming apparatus of cleaner-less system using toner particles comprising resin mother particles coated with external additives, having an adhesive force between a primary transfer member and the toner particle that is larger than the adhesive force between an image carrier and the toner particle, and an adhesive force between the primary transfer member and the resin mother particle that is larger than the adhesive force between the image carrier and the resin mother particle. As a result, a stable transfer property is provided which prevents the generation of residual toner particles. Furthermore, when images with toner particles of different colors are superposed at the transfer portion, color-to-color separation of the toner particles can be prevented by setting the adhesive force between the resin mother particles of the different colors to be larger than the adhesive force between the image carrier and the resin mother particle. |
