An apparatus for dusting printed sheets with powder contains at least one powder nozzle, an actuating element which is mounted such that it can be adjusted into a position, in which the actuating element is situated in the jet path of the powder nozzle and the powder bounces off the actuating element, and an extraction device for extracting the powder which has bounced off the actuating element. An air-conducting connection exists permanently between the powder nozzle and the surroundings of the apparatus.
