Abstract
A powder detection device includes a detection unit, a cleaning unit, and a drive unit. The detection unit includes detection surfaces provided in a storage container and enables detection of powder through the detection surfaces. The cleaning unit removes the powder from the detection surfaces by sliding along the detection surfaces. The drive unit reciprocates the cleaning unit along a path extending through the detection surfaces and differentiates a speed at which the cleaning unit is moved in a first direction along the path from a speed at which the cleaning unit is moved in a second direction opposite to the first direction.
