ABSTRACT:
An image forming device includes: a main unit; an image bearing body; a belt unit; and a tension-applying mechanism. The belt unit is detachably mounted in the main unit and has a pair of supporting rollers supporting an endless belt thereon. The endless belt has an inner circumference side that confronts the pair of supporting rollers and an outer circumference side opposite to the inner circumference side. The outer circumference side of a part of the endless belt defined between the pair of supporting rollers along an arrangement direction, in which the pair of supporting rollers are arranged, confronts the image bearing body when the belt unit is mounted in the main unit. The tension-applying mechanism is provided in the main unit. When the belt unit is mounted in the main unit, the tension-applying mechanism urges one supporting roller among the pair of supporting rollers in a direction of separating the one supporting roller away from the other supporting roller, thereby applying tension to the endless belt.
