POWDER CONVEYING DEVICE, DEVELOPING DEVICE, AND IMAGE FORMING APPARATUS

To prevent, in a storage unit storing powder such as toner, adhesion of the powder to the storage unit or a conveying member.SOLUTION: A powder conveying device has: a housing 141 including a second chamber 142 that stores toner supplied from a toner supply port 147; an admix auger 145 that extends in a direction in which a rotation shaft 145a extends, is arranged in the second chamber 142 to rotate, and conveys the toner in the second chamber 142 in the direction in which the rotation shaft 145a extends; and a coil-shaped swing member 240 that is rotated following the rotation of the admix auger 145 with one end 241 being supported by the admix auger 145, and swings the other end 242 in a direction different from the direction in which the rotation shaft 145a extends.SELECTED DRAWING: Figure 5 【課題】トナー等の粉体が収容される収容部内における粉体の収容部または搬送部材への付着を抑える。【解決手段】トナー供給口１４７から供給されたトナーが収容される第２室１４２を備えた筐体１４１と、回転軸１４５ａの延びる方向に延び第２室１４２内に配置されて回転し、第２室１４２内のトナーを回転軸１４５ａの延びる方向に搬送するアドミックスオーガ１４５と、アドミックスオーガ１４５の回転に従動して回転するようにアドミックスオーガ１４５に一端部２４１が支持され回転しながら他端部２４２を回転軸１４５ａの延びる方向とは異なる向きに揺動させるコイル状の揺動部材２４０とを有する。【選択図】図５
