PROBLEM TO BE SOLVED: To stably form an image having constant quality by preventing toner from adhering to an electrode array and making the supplying of the toner to an aperture smooth. SOLUTION: A projection section 14a is provided to a toner carrier roller 14. When the toner carrier roller 14 is rotated during the supplying of the toner to an aperture, the projection section 14a on the toner carrier roller 14 and an electrode array are contacted with each other along the rotation, then the electrode array is vibrated. As the toner is not adhered to the electrode array, to particularly a portion in the vicinity of the aperture by virtue of the vibration of the electrode array, toner flow at the aperture is not obstructed. As a result, it is possible to execute accurate flying control of the toner and to stably form an image having constant quality. |
