摘要： The image forming apparatus includes a discharge execution section for forcedly discharging toner from a developing device and forming a toner image on a photosensitive drum, in which a primary transfer roller transfers the toner image formed on the photosensitive drum by the discharge execution section by applying, to a predetermined area part of the toner image, a first transfer bias having a predetermined transfer efficiency with respect to an intermediate transfer belt and applying, to a part excluding the predetermined area part of the toner image, a second transfer bias whose transfer efficiency is at least smaller than the predetermined transfer efficiency of the first transfer bias.
