Abstract
A powder storage height detection device includes: a main body that has a transport path along which powder is transported; a powder transport unit that is disposed to rotate in the transport path and includes a transporter provided spirally around a rotational shaft; a swinging unit that comes into contact with a surface of the powder transported in the transport path, and swings by following at least a storage height of the surface; and a detection unit that detects a state of swinging of the swinging unit. The transport unit includes a non-transport portion in which the transporter is not present, and the swinging unit is located and disposed to swing in the non-transport portion, and an upper portion located above a contact portion to be in contact with the powder is configurated by an upward convex curved surface.
