Abstract
A toner conveying device includes a conveying screw and a swinging member. The conveying screw includes a shaft portion and a screw portion spirally wound around the shaft portion. The swinging member has a substantially comb shape and swings between the shaft portion and the screw portion with rotation of the conveying screw, and includes a plurality of overhanging portions arranged side by side at intervals in an axial direction of the conveying screw and a plurality of tip portions, each one of which is bent at a predetermined angle from a free end side of a corresponding one of the plurality of overhanging portions in a direction away from the shaft portion. A width of each one of the plurality of tip portions gradually increases at least from a portion to contact the screw portion toward a free end side of each one of the plurality of tip portions.
