PROBLEM TO BE SOLVED: To provide a belt control apparatus for reducing a load applied to a belt end by preventing the increase of a contact area between a rotation support member for supporting a rotation shaft and the side plate of an apparatus housing, even when a roller is inclined.SOLUTION: A belt control apparatus 6 includes: a belt member 60; a plurality of rotary bodies 61 on which the belt member 60 is wound; a rocking support member 134 which rockably supports one of the plurality of rotary bodies as a movable rotary body 61; an immovable fixed side plate 150; a skew detection member 130 which is arranged at the end of the movable rotary body 61 and detects the movement of the belt member 60 in a rotation axis direction Y of the movable rotary body 61; an inclination member 131 which is arranged between the skew detection member 130 and the rocking support member 134 and inclines a rotation shaft 61a of the movable rotary body 61 by the movement of the belt member 60 in the rotation axis direction Y; and a plurality of projection parts 132 which are formed between the fixed side plate 150 and the rocking support member 134. The plurality of projection parts 132 come into point contact with one of the fixed side plate 150 and the rocking support member 134.SELECTED DRAWING: Figure 3 |
