PROBLEM TO BE SOLVED: To provide a toner supply device which suppresses vibration by constraining a driving energy when conveying toner.SOLUTION: A toner cartridge 14 can be detachably mounted on a toner supply device A, and toner supplied from a supply port 14a of the mounted toner cartridge 14 is stored in a toner storage part 18. A driving source 21 can perform, by switching between normal and reverse rotations, an opening/closing operation of the supply port 14a by means of opening/closing of a cap 15 of the toner cartridge 14 mounted to the toner supply device A, and a conveyance operation for supplying toner from the supply port 14a in a switchable manner. A driving source control device 33 performs a PWM control of the driving source 21 so that a driving energy for the conveyance operation becomes smaller than a driving energy for performing an opening/closing operation of the supply port 14a. |
