Abstract:
1. An image forming apparatus, comprising: an intermediate transfer belt; first and second photosensitive bodies on which a toner image is formed, the first photosensitive body being disposed in the most upstream side in a proceeding direction of the intermediate transfer belt, the first and second photosensitive bodies being disposed to contact the intermediate transfer belt to form first and second transfer regions which are used to transfer the toner image to the intermediate transfer belt, and a first transfer current density of the first transfer region being greater than a second transfer current density of the second transfer region; first and second intermediate transfer members pressurizing the intermediate transfer belt to bring the intermediate transfer belt into contact with the first and second photosensitive bodies, respectively, the first and second intermediate transfer members not directly pressurizing the first and second photosensitive bodies; a first spacer concentric with the first intermediate transfer member and having a first diameter to contact the first photosensitive drum to separate the first intermediate transfer member from the first photosensitive drum at a first distance; and a second spacer concentric with the second intermediate transfer member and having a second diameter different from the first diameter to contact the second photosensitive drum to separate the second intermediate transfer member from the second photosensitive drum at a second distance different from the first distance.
