An image forming apparatus includes at least one image forming unit, a
primary transfer belt, and a secondary transferer. The image forming unit
includes an image carrier and a primary transfer bias applicator. The
secondary transferer includes a secondary transfer nip, a secondary
transfer bias applicator, and a facing member facing the second transfer
bias applicator. The secondary transfer bias applicator forms a secondary
transfer electric field. The image forming apparatus further includes a
bias applicator, a contact start site, and an electrode. The bias
applicator applies a bias voltage having a same polarity as the normal
charge polarity of the toner to the primary transfer belt, downstream of
the primary transfer bias applicator. The recording medium starts to
contact the toner image at the contact start site, located upstream of
the secondary transfer nip, where the electrode forms an electric field.
