<P>PROBLEM TO BE SOLVED: To obtain a toner supply device capable of always supplying fixed amount of toner regardless of the amount of toner in a toner bottle. <P>SOLUTION: The toner supply device 1 is equipped with the toner bottle 3 in which the toner is stored, a driving motor 35 driving and rotating the toner bottle 3, a storage part 5 in which the toner discharged by the rotation of the toner bottle 3 is stored, a piezoelectric sensor 37 measuring the weight of the toner bottle 3 and a control part 40. The toner bottle 3 is equipped with a supply port 17 for supplying the toner to the storage part 5. The control part 40 controls the driving motor 35 in accordance with the result of detection by the piezoelectric sensor 37 to change the rotational speed of the toner bottle 3 in supplying the toner from the toner bottle 3 to the storage part 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
