PURPOSE:To prevent stagnation of toner by providing a vibration providing means to shake off toner in contact with the wall face, to the wall face of a toner container or in the toner container. CONSTITUTION:A magnetic roller 32 is fitted in the outer shell 30 of the vibration providing means 20 in freely rotatable form. A part of the magnetic roller 32 is the first permanent magnet 33,and the second permanent magnet 33 is fitted to a part of the outer shell. Accordingly, when the magnetic roller 32 is rotated in a hole 34, vibration can be generated by coming near and separation of the two permanent magnets. In such a case, poles of the first and second permanent magnets may be different or the same, and the same effect can be obtained even when one of them is soft magnetic body. The driving source, i.e. a motor 35, that provides rotation to the magnetic roller exists in the outer shell 30 in sealed form, and power supply to the motor is made through a electric wire 36. |
