Abstract

A powder classifying device that classifies powder includes a mesh member having meshes, and a brush roller formed with hair-like members and configured to rotate in sliding contact with the mesh member at a predetermined portion in a circumferential direction of the brush roller to push the powder conveyed in a radial direction of the brush roller against the meshes so that the powder is classified into powder passing through the meshes and powder not passing through the meshes.
