Abstract: A supply device for supplying powder, includes: a storage part in which the powder is stored; a supply control part which is provided such that the stored powder flows therein and remains therein, and from which the powder is discharged by external force; and a supply driving part which provides force to the supply control part. The supply driving part includes a control period in which a moving speed is increased and then reduced in a process of reciprocating the supply control part. The control period is set to perform a movement by a distance which is obtained by excluding or adding a predetermined distance from or to a total distance in the process of reciprocating the supply control part.
