Abstract
An image-forming apparatus adjusts the running state of a belt by displacing one of the rolls supporting an endless belt, wherein the roll is displaced to prevent the belt from being twisted by a change in the tension of the endless belt that stems from the operation for displacing the roll. When the image-forming apparatus is provided with a belt running adjusting mechanism,which adjusts the running state of the endless belt,by displacing one (drive roll,) of plural rolls supporting the belt,in the adjusting directions J, K, there is provided a tension correction mechanism,which corrects a change in the tension of the endless belt,that is caused by the operation of the belt running adjusting mechanism,for displacing the roll,, by displacing, in the correction directions L, M, a contact member (tension roll,) which is in contact with the belt,along the direction of width thereof.
