Sieve device, supply unit, developing unit, image forming apparatus, and method of supplying toner particles

摘要

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.

1. A sieve device, comprising:
a sieve body including:
a cylinder adapted to be supplied with toner particles;a filter disposed at a bottom of the cylinder; anda blade adapted to agitate the toner particles within the cylinder to allow the toner particles to pass through the filter, the blade being rotatable about a rotation axis that intersects with the filter, and the blade is in proximity to the filter with a distance between a surface of the blade facing the filter and a surface of the filter facing the blade being within a range greater than 0 mm and not greater than 5 mm, so that the blade generates a vortex that reaches the filter when the blade is rotated; and an introduction pipe adapted to introduce the toner particles passed through the filter outside the sieve body.
