PROBLEM TO BE SOLVED: To reduce the number of component parts and to suppress noise. SOLUTION: In a power transmission device in which power is transmitted from a driving part 14 to the stirring body 6b of a toner cartridge 6 via a coupling 15 and an intermediate gear mechanism 16, the coupling 15 is formed of a coupling shaft 15c concentrically integrated with the upstream driven gear 16c of the intermediate gear mechanism 16, and the opening 37 in the leading end of the coupling shaft 15c is engaged with the drive shaft 24 of the driving part 14. |
