Abstract
A belt tension mechanism includes a tension roller disposed on a side of a photoconductive belt for pressing the photoconductive belt, a first elastic component connected to the tension roller for providing the elastic force to the tension roller, and a releasing device disposed on the other side of the photoconductive belt. The releasing device includes a actuating component for moving in a first direction and separating from the tension roller when being electrified so that the first elastic component can drive the tension roller to a position where the tension roller can press the photoconductive belt, and a second elastic component connected to the actuating component for driving the actuating component to a second direction opposite to the first direction when the actuating component is not electrified so that the actuating component can drive the tension roller to a position where the tension roller cannot press the photoconductive belt.
