Abstract:
An image forming apparatus includes a first image carrier, a second image carrier, an intermediate transfer member disposed facing the second image carrier, a conveyance belt to transport a transfer sheet, disposed facing both the first image carrier and the intermediate transfer member, a first transfer member to transfer a first toner image formed on the first image carrier onto the transfer sheet, a second transfer member to transfer a second toner image formed on the second image carrier onto the intermediate transfer member, and a third transfer member disposed downstream from the second image carrier in a rotation direction of the intermediate transfer member, to transfer the second toner image from the intermediate transfer member onto the transfer sheet transported by the conveyance belt. The first image carrier and the intermediate transfer member inflect the conveyance belt at a first inflection angle and a second inflection angle, respectively.
