Zusammenfassung:PROBLEM TO BE SOLVED: To improve an image quality and the service life, by reducing the deterioration in toner by a toner sending member, by restraining the total number of revolution by changing a rotational speed of the toner sending member with a simple constitution. SOLUTION: Cones 31 and 32 being substantially parallel in the respective rotational axes and being constant in an interval of respective side surfaces, are arranged in a driving force transmission means for transmitting driving force to the toner sending member 10b. A roller 33 for transmitting the driving force is arranged between the cone 31 and the cone 32. A position of the roller 33 is moved in accordance with rotation of the cone 31 or the cone 32. A rotational speed of the toner sending member 10b for transmitting the driving force from the cone 32, changes with an increase in a number of revolution of the driving force transmission means 30.
