The present invention relates to an image forming apparatus, comprising:
an image carrying belt which rotates so as to carry an image; a first
roller supporting the image carrying belt; a second roller contacting a
face opposite to a face of the image carrying belt contacting the first
roller, and supporting the image carrying belt; and a control unit which
controls rotation of the image carrying belt such that a portion of the
image carrying belt, supported by the first roller in a period that the
image carrying belt is stopped before image formation, is supported by
the second roller in a period that the image carrying belt is stopped
after the image formation.
