PURPOSE:To prevent the occurrence of a toner well by always and effectively vibrating the significant surface of a toner guide plate provided beneath a guide roller so that a still part doesn't exist. CONSTITUTION:The toner guide plate 17 consists of a 1st elastic member 17a and a 2nd elastic member 17b and is provided beneath the guide roller 14. Rectangular wave shaped recess and projection part provided on one edge in parallel with the toner guide plate 17 in the longitudinal direction is brought into contact with a spiler part 18a of a toner carrying screw 18 and the toner guide plate 17 is vibrated corresponding to the rotation of the toner carrying screw 18. In addition to that, any projection part of the toner guide plate 17 is brought into contact with the spiler part 18a so that the toner guide plate 17 is always vibrated. The projection parts are formed on both edge parts in the longitudinal direction of the toner guide plate 17 so that both edge parts on the other edge of the guide plate corresponding to the projection part are effectively vibrated. Thus, a corner part where toner is easily retained is vibrated so that the occurrence of the toner well can be prevented. |
