POWDER CONVEYING DEVICE, PROCESS UNIT, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a powder conveying device capable of maintaining stable powder conveying ability by preventing powder from being flocculated and stuck on the inner wall surface of a housing while securing a gap between a conveying member which conveys powder by rotation and the inner wall surface of the housing over a long term.

SOLUTION: The powder conveying device includes: the conveying member 44 having a plurality of fins 52 fixed to be spaced on a rotary shaft 50, and rotating to convey the powder in a shaft direction by the conveying action of the fin 52; and the housing 42 in which the conveying member 44 is housed, and also is equipped with: a flocculation preventing member 54 laid between the fins 52 proximately to the inner wall surface 46 of the housing 42 on the outer periphery part of the fin 52 of the conveying member 44; and a vibration generating part 58 vibrating the flocculation preventing member.
