1. An electrophotographic imaging device, comprising: a drive roll, including a drive gear coupled thereto, the drive gear having pluralities of first gear teeth; a backup roll, including a backup roll gear coupled thereto, the backup gear having pluralities of second gear teeth; an endless belt disposed about the drive roll and the backup roll at an end thereof, including a tension roll at an opposite end of the endless belt to keep in tension the endless belt about the drive roll and the backup roll at a toner transfer area, whereby rotation of the drive roll during use causes the endless belt to translate and rotate the backup roll and the tension roll; and first and second gears with pluralities of third gear teeth and fourth gear teeth, respectively, wherein the pluralities of third gear teeth of the first gear engage the first gear teeth of the drive roll and the pluralities of fourth gear teeth of the second gear engage the second gear teeth of the backup roll gear to overdrive the backup roll relative to the drive roll during use, but including a clutch between the first and second gears to limit an amount of tension in the endless belt at the toner transfer area.
