Abstract:
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.
