Abstract

Provided is a slurry cleaning apparatus which can efficiently clean a slurry containing toner matrix particles or resin fine particles in a shorter time. The slurry cleaning apparatus of the present invention comprises a cleaning chamber for contacting a slurry with cleaning water, and flow rate controllers for controlling the flow rate of the slurry. The flow rate controllers are located respectively at a slurry inlet through which the slurry is fed to the cleaning chamber and at a slurry outlet through which the slurry is discharged from the cleaning chamber. The cleaning chamber has at least one filtration side having water permeability, and is constructed so that the slurry flows at a constant flow rate in a space in contact with the filtration side, wherein the cleaning water is fed to the cleaning chamber and brought into contact with the slurry flowing in the space, and then passes through the filtration side.
