Abstract
An endless belt driving device comprises an endless belt, a driving roller for driving the endless belt, a guide member for guiding the movement of the endless belt, and a supporting plate by which the guide member is supported so as to be rotatable about an axis perpendicular to the length of the guide member. When the endless belt is laterally displaced along the guide member, a load resulting from the force of displacement causes the guide member to turn. Consequently, a force oriented opposite to the direction of displacement acts on the endless belt.
