ABSTRACT:
In a transfer unit of an image forming apparatus, an auxiliary transfer roller and a main transfer roller are provided relative to a photosensitive drum, with a transfer belt interposed. A low voltage for avoiding occurrence of a high electric field is applied to the auxiliary transfer roller, while a high transfer voltage for realizing sufficient transfer is applied to the main transfer roller.
