Abstract
A toner classification apparatus comprising a classification rotor, wherein the classification rotor comprises a first vane group containing first vanes and a second vane group containing second vanes, the second vanes have a length shorter than the first vane group; the number of second vanes, which are disposed between two adjacent first vanes, is 1 to 2, independently; each of the first vanes draws first trajectory and each of the second vanes draws second trajectory when the classification rotor rotates, a distance from the center of rotation to an outer circumference side end of the first and second trajectory are defined as L1 and L3, respectively, and a distance from the center of rotation to the center side end of the first and second trajectory are defined as L2 and L4, respectively, L1 to L4 satisfy prescribed relationships, and a toner production method using the toner classification apparatus.
