A photocopier includes a toner bottle that discharges toner from an opening by a rotation, a motor that rotates the toner bottle and a contacting section provided at a position through which a protrusion of the toner bottle passes when the protrusion comes down by the rotation of the toner bottle. When the weight of the toner bottle is more than or equal to a predetermined value, the contacting section descends by the weight of the toner bottle when the protrusion passes through the contacting section, and the contacting section ascend when the protrusion passes away from the contacting section. When the weight of the toner bottle is less than a predetermined value, the contacting section doesn't descend by the weight of the toner bottle.
