The image forming apparatus is provided with: an image carrier that
carries an image; an intermediate transfer belt that is arranged as
opposed to the image carrier, and that rotationally moves in a
predetermined direction; a primary transfer member that is arranged as
opposed to the image carrier through the intermediate transfer belt, and
that primarily transfers the image on the image carrier to the
intermediate transfer belt; a secondary transfer member that secondarily
transfers the image on the intermediate transfer belt to a recording
medium; first, second and third hanging members that hang the
intermediate transfer belt; and a drive device that transmits drive force
to the first and the second hanging members such that drive force by the
second hanging member is larger than drive force by the first hanging
member.
