11. The image forming device according to claim 1 , wherein the hardware processor gives the guidance to the user of reattachment of the new toner bottle which was previously being attached when the empty state detected by the detector is not released after toner is supplied to the toner storage from the new toner bottle and the attachment of the old toner bottle to the attaching unit is detected.

12. The image forming device according to claim 1 , wherein the hardware processor gives a guidance to the user to make a service call when the empty state detected by the detector is not released after toner is supplied to the toner storage from the new toner bottle and the detected empty state is not released even after the toner bottle is reattached predetermined times by the user.

13. The image forming device according to claim 10 , further comprising:

a display unit on which various kinds of screens are displayed to the user,

wherein the hardware processor displays a guidance screen on the display unit to make the guidance to the user.

14. The image forming device according to claim 1 , wherein the hardware processor notifies a predetermined server of an abnormality when the empty state detected by the detector is not released after toner is supplied to the toner storage from the new toner bottle and the detected empty state is not released even after the toner bottle is reattached predetermined times by the user.

15. The image forming device according to claim 1 , wherein the hardware processor:

interrupts an operation to supply toner to the toner storage from the toner bottle if a certain cause to interrupt occurs during the operation which is carried out after detection that the toner bottle attached to the attaching unit is new; and

restarts the operation after the cause to interrupt is solved.

16. A controlling method applied in an image forming device, comprising:

an attaching unit to which a removable toner bottle is attached;

a toner storage that stores toner supplied from the toner bottle attached to the attaching unit; and

a detector that detects an empty state of toner in the toner storage,

wherein the method comprises:

supplying toner to the toner storage from the toner bottle when the toner bottle attached to the attaching unit is new; and

switching a state of the toner bottle to an old state from a new state if the empty state detected by the detector is released.

17. The controlling method according to claim 16 , further comprising:

updating a remaining quantity of the toner bottle to a remaining quantity at the time of the new state when the state of the toner bottle is switched to the old state from the new state.

18. The controlling method according to claim 16 , further comprising:

maintaining the remaining quantity which was shown before the new toner bottle is attached as the remaining quantity of the toner bottle when the toner bottle attached to the attaching unit is new and the state of the toner bottle is not switched from the new state to the old state.

19. The controlling method according to claim 16 , wherein the toner bottle comprises a new and old identifying member that:

maintains the new state when the toner bottle is new; and

maintains the old state when the state is switched from the new state to the old state, and

wherein the state maintained by the new and old identifying member is switched from the new state to the old state.

20. The controlling method according to claim 19 , wherein the new and old identifying member includes a fuse, and wherein the state of the toner bottle is switched from the new state to the old state when the fuse is cut.

21. The controlling method according to claim 19 , wherein the new and old identifying member includes a storage, and wherein new product information stored in the storage is written to old product information so that the state of the toner bottle is switched to the old state from the new state.

22. The controlling method according to claim 16 , further comprising:

giving a guidance of reattachment of the toner bottle to a user when the empty state detected by the detector is not released after toner is supplied to the toner storage from the new toner bottle.

23. The controlling method according to claim 16 , further comprising:

giving the guidance to the user of reattachment of the new toner bottle which was previously being attached when the empty state detected by the detector is not released after toner is supplied to the toner storage from the new toner bottle and the attachment of the old toner bottle to the attaching unit is detected.

24. The controlling method according to claim 16 , further comprising:

giving a guidance to the user to make a service call when the empty state detected by the detector is not released after toner is supplied to the toner storage from the new toner bottle and the detected empty state is not released even after the toner bottle is reattached predetermined times by the user.
