Abstract

A development powder dispensing apparatus that is in the form of a carousel. The apparatus has a generally cylindrical configuration that is divided into a number of chambers such that the development powder toner within each chamber may be supplied individually to a magnetic brush unit. Because of the separation of the toner into chambers, no toner compression is experienced even though large amounts of toner may be stored.
