Abstract
A sheet feeder with electrostatic dust-collecting function includes a paper path, a feeding roller, a dust-collecting passageway and an electrostatic charge generator. The feeding roller located on the paper path feeds a sheet through the paper path. The dust-collecting passageway has an inlet connected to the paper path and an outlet located opposite to the inlet. The electrostatic charge generator disposed aside the outlet of the dust-collecting passageway generates electrostatic charges to attract dust coming from the sheet through the dust-collecting passageway and the paper path.
