Abstract:
A sieve device is provided. The sieve device includes a sieve body and an introduction unit. The sieve body includes a cylinder, a filter, and a blade. The cylinder is adapted to be supplied with toner particles. The filter is disposed at a bottom of the cylinder. The blade is adapted to agitate the toner particles within the cylinder to allow the toner particles to pass through the filter. The blade is rotatable about a rotation axis that intersects with the filter in proximity to the filter. The introduction unit is adapted to introduce the toner particles passed through the filter outside the sieve body.
