PROBLEM TO BE SOLVED: To provide a toner supply device capable of preventing incorrect detection of a toner end sensor by avoiding a state of sparse toner that temporarily occurs when a toner stirring member passes through a sensor face of the sensor in a hopper, the toner stirring member being provided inside the hopper, including a mylar, and capable of rotating.SOLUTION: A projection part 53 has a substantially conical shape, and is installed closer to the vicinity of the downstream side in a direction of rotation of a toner stirring member 55 than a sensor detection face 52a of a toner end sensor 52, so as to be capable of contacting a tip 54a of a mylar 54. The projection part 53 functions as a convex part provided to project toward substantially the center of a rotation shaft 55a of the toner stirring member 55 from an inner wall face of a hopper 57, so as to reduce the elastic restoring speed when the tip of the mylar 54 is released from the contact state with the sensor detection face 52a. |
