Abstract
A vibrating member (3) having an elasticity is provided in which an end (A) is mounted to a rotating part (6) in a toner conveying section (4) and which has a size such that the other end (B) thereof extends far beyond the tip of a blade (5) of the rotating part (6), whereby the rotation of the rotating part (6) causes the other end (B) of the vibrating member (3) to collide with the opening or inner wall of a toner cartridge (1). This collision allows a toner to drop efficiently, prevent the toner from being blocked, and noise to be reduced.
