Abstract
A gas current toner classifier has a material feed nozzle, a Coanda block, a classifying wedge and a classifying wedge block having the classifying wedge. The Coanda block and the classifying wedge define a classification zone, and the classifying wedge block is set up in the manner that its location is changeable so that the form of the classification zone can be changed. A method of producing toner using said classifier is also described.
