PURPOSE:To prevent entrance of toner and to prevent generation of slipping in the belt-shape photosensitive body by attaching a magnetic member to a surface of a casing in the vicinity in an edge part in the width direction of the belt-shape photosensitive body. CONSTITUTION:The belt-shape photosensitive body 2 rotating counterclockwise is provided inside a casing 1. This belt-shape photosensitive body 2 is hung by a driving roll 3 supported by casing 1, a follower roll 4 and a tension roll 5. Tension is imparted to the photosensitive body 2 with the effect of a tension spring 6 by the tension roll 5. A restriction member 10 restricting the siding of the belt-shape photosensitive body 2 is provided in the vicinity of the both edges of the inner periphery of the belt-shape photosensitive body 2. Then, the floating toner is attracted by a magnetic member 12 attached to a side surface of the casing 1 in the vicinity of the edge part of a developing roll 11 and the photosensitive body 2 to prevent the magnetic toner and carrier from entering the inside of the belt-shape photosensitive body 2. |
