An image forming apparatus includes an intermediate transfer belt; a plurality of photosensitive bodies on which a toner image is formed, wherein the photosensitive bodies are disposed to contact the intermediate transfer belt so as to form respective transfer regions which are used to transfer the toner image to the intermediate transfer belt, wherein a first photosensitive body is disposed in the most upstream side in a proceeding direction of the intermediate transfer belt, and a transfer current density of the first transfer region is greater than a transfer current density of the remaining transfer regions.
