Abstract
A dust collector includes a housing, a dust collecting bag that is installed in the housing and has an air permeability, a supply section that has a pipe coupled to the dust collecting bag, and supplies a powder into the housing via the pipe, a negative pressure generating section that generates a negative pressure in the housing, and a vibration applying section that applies a vibration to the dust collecting bag. The dust collecting bag includes a top surface, a bottom surface, and a side surface coupling the top surface and the bottom surface with each other, and a vibration transmitted to the top surface is larger than a vibration transmitted to the bottom surface.
