Transfer Belt
The Transfer Belt serves to accumulate the images produced by the four developer 
rollers before transferring the composite image to the media with the Transfer 
Roller. Components of the Transfer Belt appear below.
In addition to the Transfer Belt, a Transfer Roller (sometimes referred to as the 2nd 
Transfer Roller) transfers the composite image to the media for fusing.
