<p><P>PROBLEM TO BE SOLVED: To provide a toner conveyance mechanism capable of preventing adhesion of toner to a conveyance member without making noise to continue maintenance of suitable toner conveyance performance. <P>SOLUTION: The toner conveyance mechanism 70 includes: a conveyance spiral 72 which is the conveyance member arranged inside a housing 71 which stores the toner, and conveys the toner by rotation; and a projection 73 which is provided at an inner wall of the housing 71 to project toward the conveyance spiral 72, wherein the conveyance spiral 72 is vibrated by continuous contact to the projection 73 with its rotation. Thus, a mechanism for forcibly vibrating the conveyance spiral 72 is provided immediately near the conveyance spiral 72 in the housing 71. Consequently, impulsive sound for vibrating the conveyance spiral 72 that reaches the outside of the housing 71 is suppressed, and adhesion of the toner to the conveyance spiral 72 is prevented by an action of vibration. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
