Abstract
A belt unit includes an endless belt; multiple rollers including a tension roller that applies tension to the belt; a frame to which the multiple rollers are attached; bearing members which are movably attached to the frame and at least one of which is detachable from the frame; and urging units that urge the bearing members from the inner-peripheral-surface side to the outer-peripheral-surface side of the belt. The detachable bearing member includes a hole part that receives a rotation shaft of the tension roller and that rotatably supports the rotation shaft; and a guide surface that guides the shaft to an opening of the hole part while the bearing member is moving toward the frame against the urging force of the urging unit to be attached to the frame.
