PROBLEM TO BE SOLVED: To provide a powder conveyance mechanism that can reduce a dead space in a conveyance path of powder compared with the conventional one.SOLUTION: A powder conveyance mechanism includes a conveying member 10b that is arranged below powder and conveys the powder, and a vibration providing member that provides the reciprocating acceleration in a conveyance surface direction F2 extending along a powder conveyance surface of the conveying member 10b. The maximum acceleration a1 in the powder conveyance direction provided to the conveying member 10b by the vibration providing member is made smaller than the maximum acceleration a2 in the opposite direction to the powder conveyance direction provided to the conveying member 10b by the vibration providing member, and thereby the powder is conveyed in the powder conveyance direction by the conveying member 10b.
