Abstract: A method for detecting powder is performed in a powder detection device including a pair of electrodes arranged to be opposed to each other with a gap interposed therebetween and an electric circuit electrically connected to the pair of electrodes. The method includes detecting powder filling in a case where the electric circuit together with powder and the electrodes forms a closed circuit when the powder fills the gap.
