Abstract
A belt device includes a first stretching member and a detector. The first stretching member stretches an endless belt capable of rotational movement. The detector detects a base of the belt and/or a density of a toner image on the belt. The first stretching member includes a first parallel area that is parallel to an axial direction, which is a direction of a rotation axis of the belt, and a first inclined area that is connected to an outer side of the first parallel area with respect to the axial direction and is inclined in a direction closer to the rotation axis. The detector detects a location corresponding to a first boundary between the first parallel area and the first inclined area or a location corresponding to a predetermined first adjacent area that is adjacent to and on an inner side of the first boundary.
