Abstract
A powder container includes an inner wall, a rotation axis, and a flap to rotate about the rotation axis. The flap includes a comb-teeth tip portion to contact and slide along an inner wall surface of the powder container. The comb-teeth tip portion has teeth in which a distance from a root between adjacent teeth to the rotation axis when the comb-teeth tip portion does not contact the inner wall surface is longer than a shortest distance from the inner wall surface to the rotation axis.
