Abstract
There is described a color image forming apparatus, which makes it possible to prevent the intermediate transfer belt from slacking. The apparatus includes a plurality of image bearing members; an intermediate transfer belt onto which a full color toner image is formed; a driving roller to drive the intermediate transfer belt; a transfer unit to transfer the full color toner image onto a sheet; a cleaning unit to remove residual toner remaining on the intermediate transfer belt; a first tension applying unit, located upstream from the transfer unit in a circulating direction of the intermediate transfer belt, to apply a first tension onto the intermediate transfer belt; and a second tension applying unit, located downstream from the cleaning unit in the circulating direction of the intermediate transfer belt, to apply a second tension onto the intermediate transfer belt.
